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

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

Averaged Focal Plane Temperature

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.

Hard	3.00	5.00	Hard Photons
Harder	5.00	10.00	Very Hard photons
Hardest	10.00		Beyond 10 keV

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.

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 History

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)
