ABSTRACT
This document describes FGS-related SMOV activities, including a timeline, a brief overview of the relationship between activities, pre-requisites and scheduling requirements for
PDB and flight software updates and a compilation of the parameters. Each test is discussed in detail, including the responsible party, goals and activities, scheduling requirements, data analysis and output products.
1. INTRODUCTION
The FGS SM2 SMOV program is designed to accomplish three tasks: (1) to verify the
acquisition and tracking capability of the two original FGSs after release from the shuttle
bay, (2) to commission the new FGS for operational modes, (3) to re-establish the astrometric calibration of the astrometer FGS 3 and verify that the servicing mission has not
compromised its capabilities.
This ISR serves to describe each FGS SMOV test and responsible group, a map of the
timeline and pre-requisites, the scheduling requirements for PDB and flight software
updates and the data analysis plans.
Section 2 will describe the SMOV timeline and give a brief over-view of the relationship between activities. Each subsequent section will describe the test goals and activities,
analysis and output products, and scheduling requirements. When relevant, two proposals
are available to accommodate insertion of the new FGS in bay 1 or bay 2.
2. Proposal Summary and Dependencies
In key places, enough time is included for contingency scheduling changes of dependent tests. Also, time for PDB updates has been accommodated. The Folding Flat (FF3)
Optimization (7000, 7026), the FGS/FGS Alignment (7002, 7025), and the Mini-OFADs
are all pre-requisites for standard guiding and standard astrometry with the new FGS. The
1
products of these tests must be onboard or in the ground system before executing the Near
Term Stability Test (7003, 7027). The required order of the FGS tests are:
1. Guide Star Check [Old FGSs] (7006, 7028); proceed with SMOV if all is ok.
2. Folding Flat (7000, 7026); products in the system leaving enough time for PDB
updates and uplinks.
3. Guide Star Check [New FGS]; leave time to pull Mini-OFADs if New FGS cannot
guide.
4. Mini-OFAD (7001, 7023, 7024) & FGS/FGS Alignment (7002, 7025)
(any order for these two but their products must be in the system before proceeding
with the next FGS test),
5. the Near Term Stability Test (7003 and 7027).

3. 7004 GYRO/FHST Scale-Factor and Alignment Calibration
PI and Team Responsibility
PI: Ed Kimmer, Allied Signals Technical Services. Co-Is: D. Channel, M. Gakenheimer, A. Bradley, G. Welter, L. Hallock, PASS and PCS Team at GSFC.
Goals
This contingency proposal is required only if a gyro has been replaced. The HST will
be commanded to roll around each of its three orthogonal axes, pure pitch, yaw, and roll in
4
order to acquire the gyro data and FHST attitudes to compute the initial Gyro/FHST scalefactor/alignment matrices. The results of the analysis will be used to update the PDB and
the flight software, and are necessary for accurate HST maneuvers.
Description
Two sets of slews, separated by 24 hours to allow for PASSOPS processing, are
required. The first set will provide data to perform the calibration and the second set is
intended to verify the initial set of results. The sequence is:
1. From the Continuous Viewing Zone (CVZ), pitch 90 degrees to the Anti-sun
pointing.
2. Roll 90 degrees.
3. Roll -90 degrees.
4. Pitch -90 degrees back to the CVZ.
5. Yaw 90 degrees.
6. Yaw -90 degrees to the CVZ.
Verification slews: Same as calibration sequence above.
Note that a special series of targets had to be created to accommodate the SM2 special
Bright Earth Avoidance requirements. This made the test quite complicated. Without a
BEA requirement, pure pitch, yaw, and roll maneuvers could be described in a proposal
quite easily and efficiently. The current design however requires a specific initial pointing
in a zone which satisfies the constraints and then minimizes (but not eliminates) the Bright
Earth pointings throughout the test. Permission has been granted to violate the BEA constraints if necessary.
Data Analysis and Output Products
Data reduction will be performed by the PI and his team using PASS software. (Algorithms found in CSC PASS Requirements Specification/TM-82/6045 and PASS
Operations Manual Volume 3, Attitude Determination and Sensor Calibration Subsystem
CSC/TM-88/6103)
The initial Gyro/FHST scale-factor alignment tables are expected to be available
within 24 hours after the completion of the calibration slews. Within 12 hours after the
verification slews, the implementation of the initial tables will be confirmed and possibly a
refined result will be available. The Gyro/FHST calibration will result in the uplink of a
combination of the following tables: FMMT3G1-4 (Composite Gyro Conversion Matrix 3 Gyro), FMMT4G (Composite Gyro Conversion Matrix - 4 Gyro), FASCS (Composite
Scale Factor), FAINGC (Inverse Calibration), FMTG (Vehicle to Gyro Trans).
5
The tables are also documented in the SCHF.DAT file in the PDB: Gyro-to-Vehicle
transformation matrices GYINSC, RGAMTX, PRGAMTX. Because the PDB tables are
place holders, it is not necessary to update those before the tables are uplinked to the S/C.
Contingency
This is a contingency test to be run if one or more gyros are replaced. If this proposal
should fail, all pointing activities will be halted and trouble shooting by the PCS will
ensue.

Proposal implementation, coordination of updates.
4. 7005 FHST-TO-FGS Alignment Proposal
PI and Team Responsibility
PI: Art Bradley, Allied Signals Aerospace; Co-Is: D. Channel, M. Gakenheimer, Ed
Kimmer, G. Welter (PASS PCS Team at GSFC).
Goals
FHST-To-FGS Alignment is a contingency proposal to acquire the data to relate the
coordinate frames of the Fixed-Head Star Trackers and the FGSs. This is a variation of the
pattern match proposal and will only be executed in the event of a large misalignment
problem.
Description
The test will consist of acquisitions of guide stars in the old FGSs along with concomitant mapping with the FHST. The field is NGC3532, which has many bright stars and is
shown in Figure 2. The FGS star catalog provided to PASS by the astrometry team for OV
will be used. PASSOPS will compute the attitude and the FHST/FGS alignments. Note
that the FGS acquisitions and FHST maps will not be initiated in the STScI SMS but will
be incorporated in a special Merge SMS generated by the PCS group. The FGE K-factors
will be adjusted for this proposal and will be reset afterwards by PCS. The FGS star catalog provided to PASS by the astrometry team for OV will be used.
Data Analysis and Output Products
The following tables will be uplinked to the vehicle as a result of this test: FMVFH,
FMPSDO, FMFHV, FASCS, FAINGC. These uplink tables are the FHST to FGS transformations. Several tables in the SCHF.DAT file in the PDB will also be updated (eventually)
6
including FHST2ST. Because the PDB tables are place holders it is not necessary to
update those before the tables are uplinked to the spacecraft.
Contingency
This test requires a reasonable Gyro/FHST alignment. In the event of a failure of this
test to provide the necessary data, all HST Pointing will stop and trouble shooting will
ensue.

5. Guide Star Acquisition Verification for Old FGSs
•
7006 Guide Star Acquisition Verification for FGS 1 and FGS 3
•
7028 Guide Star Acquisition Verification for FGS 2 and FGS 3
PI and Team Responsibility
PI: Lupie, Olivia, STScI Co-I: L. Nagel, S. Holfeltz, J. Hershey, M. Wenz, G. Chapman, M. Reinhart, R. Doxsey (STScI).
Goals
After the release of HST from the shuttle bay, it is necessary to verify that the guide
star acquisitions can be performed successfully using standard operational procedure. The
alignment will be verified by using multiple guide star pairs which fall in different parts of
the pickle.
Description
Four pairs of guide stars will be acquired in FGS 1 and FGS 3 (or FGS 2 and FGS 3)
and held in fine lock for 15 to 40 minutes. Some re-acquisitions will be initiated to check
for proper removal of gyro drift. The test begins with an acquisition of a guide star pair in
the extended-CVZ (south CVZ). South CVZ was chosen to match the release attitude.
FHST update opportunities will occur prior to each ACQuisition and scheduling will be
designed to maximize TDRSS coverage. If there are pointing errors, there will be several
opportunities for the PCS team at GSFC to perform attitude updates.
Because of the motion of the BEA and the uncertainty of the launch date, four sets of
guide star pairs have been selected to cover each of the following intervals: Day 50-56,
Day 57-66, Day 68-77, Day 78-83. At least three of the four Guide Star pairs per set have
successfully achieved and held fine lock with minimal jitter during previous HST observations. Dominant and Sub-dominant FGSs will be interchanged throughout the test and all
acquisitions will use the largest search radius. The GS candidates are listed in the
Appendix.
Real-Time Requirements
The PCS group at GSFC (T. Kruz, E. Kimmer) will be monitoring the HST Pointing
Control System performance from release and throughout this test. The team will perform
standard operational procedures to recover from large attitude errors if necessary. The
STScI will be monitoring the acquisitions and tracking using software and an interface
established for the 1996 FGS alignment update activity.
8
Data Analysis and Output Products
Other than possibly accommodating a small alignment shift by increasing the operational search radius, no onboard or PDB updates are anticipated.
The PCS team at GSFC will be analyzing the performance of the PCS system using
their standard tools. The STScI will perform quick look analysis of the GS acquisition and
tracking performance using the software developed for the heptathlon analysis and support
of time critical alignment tests.
The data will be assessed off-line for optimization of operational parameters or procedures, if necessary.
Contingency
If guide star acquisitions with the old FGSs are compromised, the PCS team at GSFC
has the expertise and responsibility to trouble shoot and have done so excellently in the
past.
STScI Responsibility
Proposal implementation, quick-look real-time analysis of GS acquisition and pointing, off-line processing of GS telemetry to assess stability and accuracy of pointing.
6. Fold Flat Optimization
•
7000 FOLD FLAT 3 POSITION OPTIMIZATION FOR FGS 2R
•
7026 FOLD FLAT 3 POSITION OPTIMIZATION FOR FGS 1R
PI and Team Responsibility

HDOS, B. Clapp MOSES, O. Lupie, S. Holfeltz, J. Hershey, L. Nagel STScI.
Goals
The Fold Flat 3 (FF3) is the articulating mirror which has been installed in the new
FGS. This mirror transfers the pupil onto the Koester’s prism and the position of the beam
can be adjusted to maximize the S-curve modulation. The mirror is adjusted by ground
command (PSTOL OAMEFF3P) only. The S-curves will be optimized to achieve a modulation within 10% of the maximum accepted value at a particular field location and to
produce an acceptable set of S-curves over the entire FGS Field of View (FOV).
9
Description
The test will span several days: a single mirror move followed by a series of TRANSfer scans spread over the pickle. These data will be analyzed and the next mirror move
calculated and the sequence repeated. The last series consists of a “9 points of light” test at
the optimized folding flat mirror position. The ITS will be observed at each mirror setting,
performing a POS mode observation to determine an alignment. The steps and timing are
shown in Figure 3.
The sequence of events will be as follows. All new FGS parameters will be delivered
to STScI data bases and/or uplinked to the HST before the start of this test. Acquire transfer scan data at one position in the pickle in clear and two thirds apertures. Acquire ITS
POS mode observation. From these data, calculate revised K parameters. Require an SMS
break between this step and next to incorporate K parameters into SMS. Six to ten days
later, perform another set at the SSTS position to check for desorption effects. Twelve
hours later, make a mirror move and obtain a 5-points of light, i.e., place the star at 5 different positions in the pickle and obtain transfer scan data. Require an SMS break between
the end of this activity and the start of the next 5 points. At least 3 days later and in another
SMS, perform another 5 points of light and ITS measurement. At least 3 days later and in
another SMS, perform another 5 points of light and ITS measurement. At least 3 days after
the previous step, perform a 9 points of light. At the completion of this test, the results will
be folded into a new revised alignment matrix (TVS matrices in the SCHF.DAT) for the
new FGS. This will remove the large errors introduced by the folding flat mirror motion.
The nominal coordinates (in arc seconds) for the 9 points of light (see Figure 4) are:
XPOS_TARG=[486.4, 446.8, 279.0, 1.856, 0.0, 0.0, -279.0, -446.8,- 404.2]
YPOS_TARG=[-104.0, -153.0,- 55.50,- 65.342, 0.0, 65.3, -55.5,- 153.0, -205.1]
The target for this test must be single or have a well-behaved transfer scan signature.
Cycle 6 program 7210 will acquire data on 3 potential targets in the fall of 1996 which
will satisfy the BEA constraints during SMOV. From these, a suitable target will be
selected for this test. The targets are listed in the Appendix. The data from the Cycle 6 test
will be analyzed by the Esper/Abramowicz-Reed team and passed through their optimization software in advance of the SMOV test.

Data Analysis and Output Products
The analysis of the S-curves and determination of the optimal mirror position will be
performed by J. Esper and L. Reed using software that has been used successfully for
ground support work. The mirror position will be optimized for the entire FGS field of
view. The STScI will be prepared to compare in-flight S curves with the ground data provided by HDOS and verify results and conclusions. The Astrometry Team (F. Benedict, B.
Jefferys, E. Nelan) is also on-call to assess the astrometric quality of the S-curves.
The data reduction will be performed in near-real-time since certain K factors must be
revised and included in the processing for the next SMS. Specifically, a mirror adjustment
could result in changing Kb and possibly K1, K3, and Kz. These will be delivered to the
STScI at least 48 hours before the start of the subsequent SMS so that STScI can include
the K parameters in the SMS. The SMS will contain a special instruction to reset the values at the end of each visit. This will guarantee that a problem with the real-time activity
will affect only the visit and be corrected prior to any other activities. At the end of the test
and after the 9 points of light have been analyzed, several parameters will be optimized:
the optical FF3 mirror position, Cone 5 Obscuration, FGS 1R Magnitude Thresholds (IH,
IL), the FGS 1R K factors K1X, K1Y, K3X, K3Y, Kb, Kz, K5, K1 and K3. The K factors
must be incorporated in the SCIOPSDB before the new FGS is used for guiding or astrometry. In addition, a positional offset will be determined from the ITS measurement and
expressed in the form of an update to the FGS/FGS alignment matrix for the new FGS.
This matrix must be uplinked to the S/C also before the new FGS is used in guiding or
astrometry mode. The corresponding tables in the SCHF.DAT file are to be updated but the
update is not time critical since the data is onboard the S/C. This latter activity will require
several days, therefore the New-FGS GS Acquisition Test (7030) and the Mini-OFADs
(7001, 7023, 7024) must be scheduled weeks after the start of this test.
12
STScI Responsibility
STScI will, in tandem, compare the measured S curves to the ground test S curves as a
function of mirror position. The STScI will also facilitate the coordination of the efforts of
HDOS, GSFC, and the Astrometry team.
Contingency
In the event of a problem with the new FGS, HDOS and GSFC will have the trouble
shooting responsibilities. If necessary, STScI will pull all other SMOV FGS tests which
use the new FGS and commissioning will be postponed.
7. 7030 Guide Star Acquisition Verification for FGS 2 and FGS 3
PI and Team Responsibility
PI: Olivia Lupie, Co-I: S. Holfeltz, L. Nagel, J. Hershey, M. Wenz, G. Chapman, M.
Reinhart, R. Doxsey (STScI).
Goals
This proposal will verify the acquisition and tracking performance of the new FGS
when it is in the pointing control loop. Several subsequent SMOV tests require the use of
the new FGS as a guider.
Description
Four standard GS acquisitions will be performed using the new FGS as a guider. The
new FGS will be the dominant in some observations and the sub-dominant or roll FGS in
other observations. Special procedures are necessary to increase the secondary search radii
to 30 arcsec and to increase the coarse mode angle check to 30 arcsec. This latter limit is
the tolerance for a comparison between the observed and predicted angle between the two
guide stars. The increase in search radius is necessary to compensate for uncalibrated
alignment offsets. The Folding Flat Optimization (7000, 7026) must precede this test by at
least 7 days in order to calculate output products (the TVS alignment matrix for the new
FGS). This matrix must be onboard the HST prior to the start of this test otherwise potential misalignments could compromise the acquisitions.
A special uplink interval is requested in order to update the FGS alignment matrices
onboard the spacecraft. The PCS team will uplink PSTOL LOADFGS. The coarse mode
angle tolerance will be increased through a software patch under PSTOL SUBPCSS1.
Generic downlinks will be used for quick assessment. Guide star targets are listed in the
Appendix.
13
Data Analysis and Output Products
Other than possibly accommodating a small alignment shift by increasing the operational search radius, no onboard or PDB updates are anticipated.
The PCS team at GSFC will be analyzing the performance of the PCS system using
their standard tools. The STScI will perform quick look analysis of the GS acquisition and
tracking performance using the software developed for the heptathlon analysis and support
of time critical alignment tests.
The data will be assessed off-line for optimization of operational parameters or
procedures.
Contingency
If a serious problem occurs with the alignment of the new FGS, there is time for the
STScI scheduling team (Merle Reinhart and George Chapman) to pull the Mini-OFADs
and save the orbits. The PASS team are responsible for assessing alignment issues and
HDOS will be available to troubleshoot instrumental problems. In this event, the new FGS
will not be commissioned as a guider until the issues are resolved.
STScI Responsibility
The STScI will perform proposal implementation, quick-look real-time analysis of GS
acquisition and pointing, off-line processing of GS telemetry to assess stability and accuracy of pointing. Real-time reactions to contingency is the responsibility of the PCS team
at GSFC, however we will support any trouble shooting in any way we can.

PI and Team Responsibility
PI: A. Bradley, PCS/GSFC ALLIED SIGNAL AEROSPACE CO. Co-I: G. Welter
(PASS/PCS), E. Kimmer (PCS/GSFC), O. Lupie, L. Nagel, S. Holfeltz (STScI).
Goals
The goals of the Mini-OFAD are three fold: (1) to determine operational distortion
coefficients for the new FGS and update those for the old FGSs in the event that the SM2
created changes in the FGS performance, (2) to determine the star selector servo offset
biases for all three FGSs, and (3) to assess the status of the FGS 3 calibration and the
14
impact of any changes on astrometry. The small number of stars per orbit however is not
conducive to re-calibrating FGS 3.
Description
Approximately 20-24 stars in an astrometric cluster M35, spread throughout the
pickle, will be observed in POS mode in F583W with fine lock guiding. The plates are
given in the Appendix. (Compare to proposal for identification.) Two or three check stars
will be observed on multiple occasions during each orbit to track thermally (or other)
induced position drifts. A total of 5 orbits of data per FGS (as the astrometer) will be
acquired. The science data collection is standard astrometry. Because the new FGS is
being used both as the guider and an astrometer sometime during these three tests, the
acquisition distance, the secondary search radius, and the coarse mode angle tolerance will
be increased to accommodate a large uncertainty in the alignment of the new FGS. The
coarse mode angle tolerance will be patched via PSTOL SUBPCSS1 for the duration of
the three Mini-OFADs.
Data Analysis and Output Products:
The goal of the analysis is to produce relative distortion coefficients and star selector
offsets which are consistent with operational requirements. The data for the three FGSs
will be reduced by G. Welter and E. Kimmer (PASS/GSFC). We will supply the data also
to the Astrometry Team for their assessment, especially the FGS 3 data. Our goal is to
determine the state of the calibration of FGS 3, after the SM2. The following tables/
parameters may be uplinked to HST as a result of the Mini-OFAD calibration: FOCD0111 (Optical Distortion Coefficients), FSSSDA, FSSSDB (Deflection Angle A and B),
FVTABO (Star Selector A and B), FVGOPT (Nominal Optical Gain Table), FSIGPT
(Optical Gain Tables), FSGOM1 (Function of Optical Gain Table), FVUQU1, 2, 3, 4, 5
(Deflection Angle Tables), FAARG, FABRG (Deflection Angle/Optical Gain), DATER1-8
(Deflection Angle Function), the PMT calibration which provides the guide star acquisition thresholds in the PDB.
The corresponding PDB SCHF.DAT tables/parameters which will be updated at a later
time are: OPTCOEF, XDCOEF, YDCOEF, OPTOD2U, (the various distortion tables),
ALEVER and BLEVER (deflection angles), SSOFFA and SSOFFB (star selector offsets,
CPORT2 (the K factors), FIDFGS and FIDMAG (FGS PMT counts vs. magnitude), GM
(optical magnification). Because the PDB tables are place-holders, it is not necessary to
update those before tables are uplinked to the spacecraft. Generic uplinks (after the FGS
alignment calibration) will be used to load the onboard tables.
15
STScI Responsibility
STScI will work in conjunction with the Astrometry Team and the Goddard PIs to
reduce and assess the data.
Contingency
If it is operationally-impacting, a problem must be assessed by PASS and PCS at
GSFC. If the problem has astrometric impact, STScI will work with the STAT to devise a
distortion calibration plan. The impact to Cycle 6 proposals will be assessed.

PI: R. Chapman Allied Signal Technical Services Co-I: L. Abramowicz-Reed, K.
Chisolm (HDOS), G. Welter (PASS), O. Lupie, L. Nagel, S,. Holfeltz (STScI).
Goals
The FGS alignment test obtains POS mode data on an astrometrically known cluster
NGC5617. The goal is to determine the relative alignment of the new FGS with respect to
the system defined by the old FGSs. The test will also serve as a diagnostic in the event
that the old FGSs are no longer aligned as a result of SM2.
Description
The new FGS will be used as the astrometer (to minimize those special procedures for
increasing angle tolerances if it is used as a guider). Eight or nine astrometric targets,
spread across the FGS pickle will be observed in POS mode in the PUPIL filter. The
PUPIL filter is used during nominal operations. A set of guide stars which are also astrometric cluster members will be used in fine lock during the astrometric measurement.
Each orbit, the same 8 or 9 target stars will be observed but with a different set of astrometric guide stars spread across both guiding fields of view. Four orbits of data will be
obtained in this way. The astrometry targets and guide star patterns are shown in Figure 5
and Figure 6. Both the guide star telemetry and the astrometry data will be analyzed to
extract the relative alignment of the new FGS and to verify the stability of the alignment of
the remaining FGSs. The targets and guide stars are listed in the Appendix.

Data Analysis and Output Products
The test will result in the update of the following onboard software tables: FMTVT
(FGS/Vehicle Transformation), FPVXTP (FGS Frame Quaternion Transformation),
FSSSDA, FSSSDB (Deflection Angle A and B), FVTABO (Star Selector A and B offsets),
FVGOPT (Nominal Optical Gain Table), FSIGPT (Optical Gain Tables), FSGOM1 (Function of Optical Gain Table), FVUQU1, 2, 3, 4, 5 (Deflection Angle Tables), FAARG,
FABRG (Deflection Angle/Optical Gain), DATER1-8 (Deflection Angle Function). In
addition, the SCHF.DAT file in the PDB will also require update of the TVS matrices,
however the ground based file is a storage area and need not be updated in conjunction
with the scheduling of any other tests.
The alignment data will be reduced using the PASS alignment algorithms, by G. Welter and E. Kimmer at GSFC. The alignment algorithms may be found in the PASS
Requirements Specification.
Contingency
If the alignment is changed considerably (and this is not expected) the aperture files
will require modification and the procedures established during the 1996 FGS alignment
update will be followed. The GSFC team will be responsible for producing the revised
FGS alignment matrices, the FHST and Gyro transformations and all other relevant tables.
STScI Responsibility:
If the test runs as expected, the vehicle V2V3 reference frame will not be altered.
Therefore, the SI aperture positions within this reference frame will not be altered. The
data and output products will be handled by the GSFC team. The STScI is responsible for
verifying the impact of the alignment on the SIs by monitoring the SI pointing and alignment activities after the FGS alignment has been uploaded. SMOV tests being run after the
FGS alignment will be carefully monitored.
If a global alignment problem occurs, the STScI will respond by helping to assess the
impact, propagating alignment offsets to the SI aperture positions and carrying out all
activities associated with an FGS alignment change. The steps have been performed in
1996 and documented in several memos.

PI and Team Responsibility
PI: O. Lupie STScI Co-I: J. Esper, G. Welter, J. Hershey, E. Nelan, S. Holfeltz, L.
Nagel.
Goals
The goals are threefold: (1) to establish the baseline Long Term Stability measurement
for the new FGS and monitor changes in the relative plate scale and distortion since the
SMOV Mini-OFAD; (2) to monitor changes in the transfer function on an orbital time
scale and over weeks; (3) to monitor desorption changes in the position of the ITS.
Description
The test consists of four parts. Part I: Upgren-69, the Transfer Mode calibration standard will be observed in the F583W and the Pupil to establish the baseline calibration.
Also, the target used in the Folding Flat Optimization proposal will be observed in Transfer Mode to perform trend analysis. Part II: one orbit from the Mini-OFAD will be
repeated for trending and to establish an LTSTAB baseline. Parts II through IV use the
M35 field. Part III: investigates the POS mode stability of the new FGS by acquiring data
on 3 stars spread across the pickle. These three stars will be observed over and over for 2
orbits. Part IV contains two orbits of repeated Transfer Scan observations of the star in the
central region of the pickle. Finally, the ITS will be observed in POS mode for trending.
Data Analysis and Output Products
The output products are the initial performance characteristics: short term (orbital)
spatial and temporal stability measures, and monthly trend of desorption affects on both
POS and TRANS mode. In addition baseline TRANS and POS observations will be
obtained. The TRANS mode data will be reduced and analyzed by the STScI, GSFC/
HDOS teams and the Astrometry Team. The POS mode data will be reduced and analyzed
by the GSFC and Astrometry Team supporting SMOV.
Contingency
By the time this test is executed, we will understand the operational capability of the
new FGS. The results of this test will be used to assess stability and monitor desorption
effects. The results will also be used to help in the design of an astrometry calibration plan
for the new FGS.
STScI Responsibility
STScI will reduce and analyze the transfer scan data; will analyze the POS mode
reduced data which will be supplied by the astrometry team. The STScI will have the
19
responsibility to collate the opinions of HDOS, STScI and Astrometry recommendations
on the performance of the new FGS.

Appendix
A-1. Programs 7028 & 7006: Guide Star Verification For Original FGSs
After the release of HST from the shuttle bay it, is necessary to verify that guide star
acquisitions can be performed successfully. Four pairs of guide stars will be acquired in
FGS 2 and FGS 3 (for program 7028; FGS 1 and FGS 3 would be used for program 7006)
and held in fine lock for 15 to 40 minutes. Some re-acquisitions will also be performed.
This test must be executed in the Bright Earth Avoidance (BEA) zone, the position of
which is a function of time. Because of the motion of the BEA and the uncertainty of the
launch date, four sets of guide star pairs have been selected to cover the following intervals: days 50-56, 57-66, 68-77, and 78-83. At least three of any set of four Guide Star
pairs have successfully achieved and held fine lock with minimal jitter during previous
HST observations. The Guide Star pair candidates are listed in Table A-1.

A-2. Programs 7026 & 7000: Fold Flat 3 Optimization Test
This test must be performed in the BEA (Bright Earth Avoidance zone). The standard
FGS calibration star Upgren 69 does not meet this requirement. Consequently, three targets were identified which are believed to meet all the necessary criteria; these targets,
their positions and magnitudes are listed in Table A-2. Cycle 6 program 7210 is to be executed in November 1996 in an attempt to ascertain the singularity or duplicity of the
possible targets. This information will be used to choose the final target for the Fold Flat 3
Optimization program.

A-3. Program 7030: Guide Star Acquisition Verification Test For The
Replacement FGS
This proposal will verify the acquisition and tracking performance of the new FGS
when it is in the pointing control loop. The proposal consists of four guide star acquisitions and fine lock tracking using the new FGS as a guider. Each Guide Star pair is
acquired twice with the roles of dominant and sub-dominant FGS alternating with each
acquisition. The Guide Star pairs to be used (depending on which FGS is replaced) are
listed in Table A-3.

This test acquires the data needed to calculate the FGS/FGS alignment calibration
using an astrometrically calibrated field. The replacement FGS will be used as the astrometer and the two remaining original FGSs as guiders. The astrometer will observe several
22
stars across the pickle in POS mode. For each sweep across the pickle, a different pair of
guide stars will be used. The guide star pairs, which will be distributed across the pickles,
are listed in Table A-4.

A-5. Programs 7001, 7023 & 7024: Optical Field Angle Distortion
Calibrations
Each of the OFAD programs consists of five visits to be exectued in five contiguous
orbits. Approximatley 20-24 observations will be made per visit of targets in the astrometric cluster M35. The targets are distributed over the entire field of view. A summary of the
observations on a visit by visit basis, along with the target number and corresponding
Guide Star Catalog number (when available) is given for programs 7001, 7023, and 7024
respectively, in Table 6, Table 7, and Table 8 below. The target distributions for the first of
the five visits for programs 7001, 7023 and 7024 are shown below in Figure A-1,
Figure A-2, and Figure A-3, respectively.
