- ACIS DOSE registered-photon-map
The steps we took to compute the dose map are;
- Level 1 Event files for a specified month are obtained from archive.
- Image data including I2, I3, S2, S3 CCDs are extracted from all event files.
- All the extracted image data were merged to create a month long exposure map for the month.
- The exposure map is opened with ds9, and check a distribution of count rates against energy.
From this, estimate the upper threshold value. Any events beyond this upper threshold are
assumed erroneous events such as bad pixels.
- Using this upper threshold, the data is filtered, and create a cleaned exposure map for the month.
- The exposure map from each month from the Sep 1999 is added up to create a cumulative exposure
map for each month.
- Using fimgstatistic, we compute count rate statistics for each CCDs.
- For observations with high data drop rates (e.g., Crab nebula, Cas A), we corrected the
observations by adding events.
Note: Counts and RMS's of Cumulative maps are lower than the previous months. This is because we excluded
extreme outliers.

- The Mean Detrended CTI
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
- Focal Plane Temperature
The Mean (max) FPT: -116.17 C std dev: 2.44
mean width: 0.57 days std dev: 0.40
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 following is a plot of focal plane temperature and sun angle, earth angle, and altitude.
- Bad Pixels
The plots below were generated with a new warm pixel finding script. Please see
Acis Bad Pixel Page
for details.

Acis Count Rate Plot
This monitors the ACIS count Rate vs. EPHIN count Rate.
No sources or CTI observations are removed. For daily updates see:
Ephin/Acis Info
- Science instrument background rates
This page shows scientific instrument background data based on Acis
observations. A source region file is generated using get_srcregions
and then the input event file is filtered using the regions in that file
to remove the sources.
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 |
HRC
Gratings
- Focus
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.

PCAD
Fid Light Drift
Fid light positions on ACA drift with time. The drift trends of Fid light 2 with
ACIS-I and ACIS-S configurations are shown below.
The top panel shows Fid light 2 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 0.5 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 (September 1, 2003)
indicates a transition date of use of IRU-1 to IRU-2.

Radiation Zone Timing
Plotted below are radiation zone timing plots based on the following definitions of radiation zone:
RADZONE - Ephin levels (in any of the E1300,P4GM,P41GM channels) are more than 1/3 of RADMON safing thresholds.
RADMON - Radmon is disabled for radiation zone (as commanded based on OFLS model, for comparison with actual radiation levels).
PERIGEE - Time of closest earth approach (for comparison).
