MTA Monitoring Report 08/23/02 - 08/29/02

Archive of monthly reports

Radiation

The observing schedule was interrupted following a high radiation event at 2002:236:02:11 (Aug 24).
Loads were restarted at 2002:237:13:50 (Aug 25).
Lost science time: 115.34 ks.
Obsids affected: 2783, 2541, 2683, 4362, 3015, 3009.

Due to a weak shock (likely from Aug-24 X3), Acis alert was issued on Tue Aug 27 02:40:02. ACIS fluence = 1.00e+09 p/(cm^2-sr-MeV). However, the effect was minmum, and no observation was interrupted.

Detrended CTI

CTI analysis is now computed with "detrending" derived from reject counters for all imaging CCDs

Average of ACIS-I CCDs (MnKa) slope 1.063e-8 CTI/day
Detrended slope 1.045e-8 CTI/day

ACIS Warm Pixels

The following pixels consistently showed a bias level more than 5 sigma away the chip's mean level during this period.
We suspect some of the recurring bad pixels may be due to biases which are taken just after perigee, when the focal plane is somewhat warm. For more information see the link above and MTA monthly reports.
