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
The Mean (max) FPT: | |
---|---|
-114.58 | +/- 4.09 C |
Mean Width: | |
0.43 | +/- 0.48 days |
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.

SSoft | 0.00 | 0.50 | Super soft photons |
Soft | 0.50 | 1.00 | Soft photons |

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.
Plotted below are radiation zone timing plots based on the following definitions of radiation zone:
