We report CTIs with a refined data definition. CTIs were computed for the temperature
dependency corrected data.
Please see
CTI page
for detailed explanation.
CTI's are computed for Mn K alpha, and defined as slope/intercept x10^4 of row # vs ADU.

The following is a plot of focal plane temperature and sun angle, earth angle, and altitude.
Name | Low (keV) | High(KeV) | Description |
---|---|---|---|
SSoft | 0.00 | 0.50 | Super soft photons |
Soft | 0.50 | 1.00 | Soft photons |
Med | 1.00 | 3.00 | Moderate energy photons |
Hard | 3.00 | 5.00 | Hard Photons |
Harder | 5.00 | 10.00 | Very Hard photons |
Hardest | 10.00 | Beyond 10 keV |
The following three plots show trends of SIB from year 2000. CCDs shown here are CCD3, CCD5, and CCD7. Fitted lines are linear fit after eliminating extreme outliers. For >10 keV plots, 2 lines are fit. One is with a 13 keV filter, and another without.
We collected data from acis histogram mode data, and created trend plots of peak portions and peak widths against time (DOM). The peaks were estimated by fitting a simple Gaussian on three peaks (Al, Ti, and Mn), and the widths were estimated by a width at the half max from the peak.
All histogram data are taken under TIMED and GRADED_HIST mode, SIM position is at an external calibration source position, the focal temperature is around -119.7 C, and parameter settings in aciselec, acistemp are set to about same for all.

We display a max dose trend plot corrected for events that "pile-up" in the center of the taps due to bad position information.
