MTA Monitoring Report 06/13/03 - 06/19/03
Archive of all weekly reports
Archive of monthly reports
Following the warm-restart of IRU-1 gyro-1 on 13 June, its current has
returned from the restart value of ~100 mA to approximately the same
level as prior to the warm-restart (~140 mA). This behavior is
consistent with a trend towards eventual out of spec (anomalous)
performance and the team is currently assessing a swap to IRU-2 in
order to retain maximum operational lifetime on gyro-1. IRU-2 has
continued to operate in parallel with IRU-1 and the initial
calibration was completed last week without impact to operations.
Quiet.
CTI analysis is now computed with "detrending":
Detrend CTI = Measured CTI + S3 amplitude reject rate * Detrend factor.
Average of ACIS-I CCDs (MnKa) slope 8.152e-9 CTI/day
Detrended slope 8.417e-9 CTI/day

The gyro bias level has remained unaffected by the
change in current and so to date, there has been no impact to science
or operations.
"Prob" means that there was probably bad time data included in the manual runs.
This will be corrected in future processing.
