Radiation

Due to the January 19th's M3-class flar, SCS-107 was executed on 2012:023:06:00, just prior to a rad-zone entry. The normal operation was resumed after exiting another rad-zone at 2012:026:08:27.
Lost science time: 192.1 ks.
See details in Science Run Interruption Page.

Detrended CTI

Although we have quoted CTI values of the cleanest data (FT <= -119.7 C, int time > 7000sec), the data fills these conditions are getting rare. We quote CTI temperature factor corrected ones. The values in the parentheses are CTI based on the cleanest data.

Average of ACIS-I CCDs (MnKa) slope:	2.166e-5 CTI/day	(1.274e-5 CTI/day)
Detrended slope:	6.990e-5 CTI/day	(7.068e-5 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, 5 peaks are observed.

Day (DOY)	Temp (C)	Width (Days)
20.70	-117.78	2.28	the peak started in 2012:018
20.87	-117.61	0.06
23.25	-117.65	1.19
23.52	-114.58	0.11
26.17	-114.22	0.09

Weekly focal plane temperature with sun angle, earth angle, and altitude overplotted. Sun angle is the solar array angle, that is the angle between the sun and the optical axis (+X axis). The earth angle is the angle between earth and the ACIS radiator (+Z axis). Altitude varies from 34 kkm to 128 kkm.

Min/max envelopes in dark blue appear on the trending plots. The envelopes are 4th degree fits to the monthly minimum and maximum values for each MSID. The final polynomial form and binning are still being experimented with. We will soon add to the trending pages a report of the fits and predictions they give on future limit violations. The light blue curve is our original smoothing of all the data over 30 day moving boxcars. The green/yellow line is a linear fit to all the data; the break occurs at a limit change.
