MTA Monitoring Report 07/25/03 - 07/31/03

Solar proton flux was very high over July 25-27, and a radiation alert was issued. No observations were, however,interrupted.

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 8.267e-9 CTI/day
Detrended slope 8.345e-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.
