Changes after review meeting
1- Change power off FUV and EUV slit
position from occultation to lo_res.
2 - Divide IPM/ISW activity into three
sub-activities: 2 hours at hi_res, 2 hours
at occultation, 18 hours at lo_res for both
the FUV and the EUV channel.
3 - Correct nomenclature and headings.

1.12 TEST NOTES
In the UVIS OASIS-CC application, the decomposition of the slits positions in the science
header in incorrect.
In the RAM code the "rejected command count" is cleared after a housekeeping packet has
been acquired by CSD. It should work like the "accepted command count" (roll over at
256).

The UVIS Earth sequence is part of two C15 mini-sequences and will also be in a minisequence sequence in C16. The UVIS IEBs are loaded from the first C15 mini-sequence.
The first mini-sequence in C15 will cover from turn on until approximately doy 237 (end of
the continuous DSN coverage). The second C15 mini-sequence with cover from doy 237
until the end of the C15 sequence. The C16 mini-sequence covers the start of the C16
sequence until instrument power off

2.2 ACTIVITY CONSTRAINTS
The post-Earth activity is constrained by a limited downlink capability during the period
ranging from the end of the 14.22 kbps period to the HGA-to-Earth period. UVIS has been
allocated an average of 242 bps for all the post-Earth activity.

2.3.5 IPM/ISW OBSERVATION
The IPM/ISW activity is divided into three sub-activities that use the same configuration
except for the EUV and the FUV slits. Every 22 hours is divided in 2 hours (i.e., one
integration) using the high resolution slit, 2 hours (i.e., one integration) using the
occultation slit and 18 hours (i.e., 9 integration) using the low resolution slit.

Done from 3/22/99 to 3/29/99. The names of the files recorded during the sequence
validation are:
Message log files: f99_mar_22_21_57_14.event_messages
Telemetry log files: f99_mar_22_21_57_14.telemetry, f99_mar_25_16_34_05.telemetry,
f99_mar_26_17_08_03.telemetry and F99_mar_27_16_33_22.telemetry
Note: the TCP/IP connection between the EGSE and the RTIU was lost several times
during the 7-day test, resulting in loss of science data and the creation of several telemetry
files.
