MTA Monitoring Report 01/17/03 - 01/23/03

There were several DPA panel temperature limit trips this week due to long duration observations (Orion Nebula Cluster) at undesirable pitch angles.

There were several reaction wheel speed limit violations as expected due to the temporarily increased auto-unload momentum tolerances.

Radiation

Quiet

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 9.011e-9 CTI/day
Detrended slope 9.219e-9 CTI/day
