ACIS
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.

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

ACIS Rejected Events
The links below are plots of stat1 quantities, showing on-board rejected events. The average EVTSENT, DROP_AMP, DROP_POS, DROP_GRD, THR_PIX, and maximum BERR_SUM obtained from L1 acis*stat1.fits files are plotted for each observation. CTI observations are plotted separately from regular science observations.
Column definitions:
- EVTSENT - number of events sent in data record
- DROP_AMP - number of discarded events due to corrected amplitude
- DROP_POS - number of discarded events due to CCD position
- DROP_GRD - number of discarded events due to grade code
- THR_PIX - number of pixels above respective threshold level
- BERR_SUM - number of pixel bias errors so far in science run
Note the half-life decline of the CTI source is clearly evidenced in the steady janline of EVTSENT.

ACIS Gain Trends
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.

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)
