MTA Monitoring Report 07/26/02 - 08/01/02

Archive of monthly reports

We note that the HETG insertion angle has gone down by 1 bit (6.34 to 5.96) long after the insert move had been completed during this week's gratings observations. We think that it is following the long term trend towards smaller pot angles, but are looking more closely. See Gratings trends and Gratings insertion/retraction statistics.

Radiation

Two more flares were observed, but no alerts were issued during this period.

Detrended CTI

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

Average of ACIS-I CCDs (MnKa) slope 1.024e-8 CTI/day
Detrended slope 1.009e-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.

Recent Observations

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