Upcoming Ops Requests
• All planned SMOV COS-related Ops Requests are
completed
7
Reference File Deliveries
• SMOV-derived Sensitivity Reference Files
– FUV and NUV FLUXTAB files
– Initial deliveries based upon one epoch of one standard star
• Refined delivery anticipated ~15 Oct based upon additional standard stars
– Planned for use in pipeline calibrations starting with 264 SMS
• Wavelength Calibration Reference Files
– SMOV-based wavelength parameters file delivered (FUV/NUV)
• Includes PSA/BOA/WCA and background extraction boxes and related parameters
– FUV Template Spectra and Dispersion Relations
• Ground calibrations updated for on-orbit mechanism adjustments
• SMOV-derived files to be delivered by ~15 October
– Planned for use in pipeline calibrations starting with 257 SMS

COS SMOV to-date Blind Pointing Analysis
•
First Acquisition
Stage Slew Analysis
– Include all initial
ACQ/SEARCH
and initial
ACQ/IMAGE
centering slews
– Cumulative
centroid is at
approximately +0.3
arcsec in both
along-dispersion
(AD) and crossdispersion (XD)
directions; sigma
~0.4 arcsec in both
coordinates
– No clear indication
of time-evolution
of centroid
9
COS Blind Pointing Analysis
•
First Acquisition Stage Slew Analysis: Day 236-250
– Evaluate at one-week intervals to assess possible start of trend
– No significant difference in centroid or distribution for this sampling relative to
two-week sampling
– Continue to review: possible SIAF update is required
