Radiation

Quiet

ACIS/Radiation Environment correlations

CTI Trend

Average of ACIS-I CCDs (MnKa) slope 1.276e-8 CTI/day
Detrended slope 1.215e-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.

ACIS Focal Temperature

After a month of absence, a normal periodical peak was finally obsereved this period
