We updated ACIS cumulative dose map from this month. The steps we took to compute a new dose map are;

We report CTIs with a refined data definition. CTIs were computed for the temperature dependency corrected data. Please see new CTI page for detailed explanation. CTI's are computed for Mn K alpha, and defined as slope/intercept x10^4 of row # vs ADU. Data file here
The Mean (max) FPT: -116.95 std dev: 1.48 mean width: 0.52 days std dev: 0.24
The plots below were generated with a new warm pixel finding script. Please see Acis Bad Pixel Page for details.
Front Side CCDs
Back Side CCD (CCD5)
Name | Low (keV) | Hight(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.
From this month, we trend 10th brightest data points instead of the maximum. This makes the maximum trend values to be about 20% lower than the previous months.

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

Fid light positions on ACA drift with time. The drift trends of Fid light 6 with ACIS S configuration are shown below.
The top panel shows Fid light 5 drift in ACENT I (app. along with -Y axis), and the
bottom panel shows that in ACENT J (app. along with Z axis). The unit is a pixel, and
one pixel is approximately 5 arcsec. The slope listed at the top right corner is
the change in a position per year (arcsec/yr). The vertical line on DOM = 1411 (June 1, 2003)
indicates a transition date of use of IRU-1 to IRU-2.
