Radiation

A Radiation violation of P3 (130Kev) was observed by ACE on Mon, 13 Sep 2004 at 21:35 UT.
Observed = 3.8094e+08
(limit = fluence of 3.6e8 particles/cm2-ster-MeV within 2 hours)

SCS107 ran autonomously on Mon, 13 Sep 2004 at 21:38 UT. EPHIN channels P4GM and E1300 both exceeded thresholds at about the same time.

Lost science time: 77.6 ks

Detrended CTI

CTI page was updated. The top panel shows an example of detrended CTI measurements from the front illuminated CCD3 Node 0. The top plot is all data points without any temperature dependency correction. The middle plot is data with the focal temperature equal or colder than -119.7 C, and the integration time longer than 7,000 sec. The bottom plot is all data with the temperature correction.

The values quoted below are temperature factor corrected ones.
Average of ACIS-I CCDs (MnKa) slope 5.949e-9 CTI/day
Detrended slope 6.748e-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.
