MTA Monitoring Report 05/23/03 - 05/29/03

Several alerts were issued on 2003:149 (May 29) due to an elevated radiation environment. Total orbital attenuated dose was about 5.63e+09 p/cm^2-sr-Mev, resulting in a ground commanded activation of SCS107 at 149:21:47:28 UT.
Obsids affected: 4175, 3871, 4188, 4096, although a definitive restart time is yet to be determined.

Detrended CTI

CTI analysis is now computed with "detrending":
Detrend CTI = Measured CTI + S3 amplitude reject rate * Detrend factor.

Average of ACIS-I CCDs (MnKa) slope 8.316e-9 CTI/day
Detrended slope 8.558e-9 CTI/day

IRUs

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.

Recent Observations

"Prob" means that there was probably bad time data included in the manual runs. This will be corrected in future processing.
