MTA Monitoring Report 06/14/02 - 06/20/02

Archive of monthly reports

A real-time procedure was completed successfully on June 17 to check the bright earth limb limitation with the aspect camera during perigee passage. One issue identified during the procedure was that a series of hardware commands sent from the daily load to the aspect camera to acquire monitor windows was not executed. The issue is under investigation.

Radiation

Quiet

Detrended CTI

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

Average of ACIS-I CCDs (MnKa) slope 1.025e-8 CTI/day
Detrended slope 9.792e-9 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.
