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

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.

Gratings Resolving Power

We plot E/dE vs. E for fits to detected lines with fwhm_error/fwhm less than 0.15 for the plus and minus arms of HEG, MEG, and LEG. Also shown are conservative (dotted line) and optimistic (dashed line) pre-launch resolving power expectations.

We have selected only calibration observations of Capella, HR1099, and Sigma Gem. See MIT technotes for a parallel analysis.

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)

SIM Shift and Twist

SIM Shift and Twist Trend The following plots show trends of SIM shifts (dy and dz) and twist (dtheta). All quantities are directly taken from pcaf*_asol1.fits files. The units are mm for dy and dz, and degree for dtheta. We fit three lines separated before and after (Days of Mission)= 1400 (May 21, 2003), 2700 (Dec 11, 2006), and 4400 (Aug 07, 2011). The unit of slopes are mm per day or degree per day.

The sudden shift around DOM = 1400, 2700 and 4400 are due to fid light drift (see a memo by Aldcroft fiducial light drift). On the dtheta plot, two tracks are clearly observed. The track around 0.01 is due to HRC-I, and all others are clustered around -0.002. For more detail, please see SIM Shift and Twist Trend page
