Radiation

A large active region stretching 15 Earth-diameters emitted three major halo CMEs in this period. The first of them was observed on 07/15, the second one was on 07/16, and the last one was 07/18.
As a result, SCS 107 ran at 2002:198:12:32 (autonomous EPHIN trip). A radiation violation of p3 (130keV) had been observed by ACE at the level of 3.9284e+8 on 2002:198:15:10 (UT) (shock wave) . Observations restarted at: 2002:199:15:40:29.507. A total of 87 ks of science time was lost (plus manuvers).

ACIS/Radiation Environment correlations

Detrended CTI

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

Average of ACIS-I CCDs (MnKa) slope 1.013e-8 CTI/day
Detrended slope 9.917e-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.



ACIS Focal Plane Temperature

For this period, 3 peaks are observed.

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