M&TA February 2019 Monthly Report

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.

HRMA Focus

Plots below show various characteristics of detected imaging sources. Standard level 2 data products (*src2.fits) are used. Only observations with focus (sim_x) within 0.01 mm of nominal value for given SI configuration are used. Sources are also filtered for strength (SNR > 15).

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 Trends pages.
