Radiation

Quiet
At approximately 1600 UTC on 02/04/2004) real-time proton data from the failed EPAM LEMS30 instrument were replaced with similar proton data from the LEMS120 sensor, restoring coverage in 3 channels at 47-580 keV. Our real-time ACE monitoring and alerts reflect the change. We are carefully watching the data for the next two weeks to determine any shifts required in alert trigger levels.

Detrended CTI

From this week, we report CTIs with a refined data definition. CTIs were computed for the data taken during the focal plane temperature ≤ -119.7 C, and the integration time longer than 7,000 sec. This eliminates a CTI temperature dependency, and the shows CTI degradation with time much more cleanly. Please see new CTI page for detailed explanation. For the next few weeks, both old and new CTI will be shown for comparison.

New CTI Computation
Average of ACIS-I CCDs (MnKa) slope 6.986e-9 CTI/day
Detrended slope 7.331e-9 CTI/day

Old CTI Computation
Average of ACIS-I CCDs (MnKa) slope 8.443e-9 CTI/day
Detrended slope 8.529e-9 CTI/day

ACIS Warm Pixels

We display all bad pixels showed up in past, and, if any, previously unknown bad pixels appeared in the last 14 days. We also list hot pixels (defined as 1000 above the average of bias background). Warm columns 509-514 are probably due to a computational artificial effect due to boundaries.


ACIS Focal Plane Temperature

For this period, 4 peaks are observed.

Recent Observations

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