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. Data file: here

Mean Width: | |

We are using 10 period moving averages to show trends of peak temperatures and peak widths. Note, the gaps in the width plot are due to missing/corrupted data.
The plots below were generated with a new warm pixel finding script. Please see Acis Bad Pixel Page for details.
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 |
We computed ACIS gain and offset from ACIS event1 files used in CTI computation, following the step described by C. Grant ACIS gain @ -120C page.
Instead computing gains and offsets from individual observations, we combined all data from each month and computed an monthly averaged gain and offset.
The following plots show CCD3 and CCD5 gains and offset trends.

We plot the width of the zero order streak of ACIS/HETG observations and the width of the zero order image for HRC/LETG observations of point sources. No significant defocusing trend is seen at this time. See Gratings Focus pages.
