Configuration/Radiation Overview for Aug 2009

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.
  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: -117.62 C    std dev: 1.36		
                 mean width:    0.63 days std dev: 0.67
  

  
  
  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.

  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.

  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. (NOTE: the figures are not updated from Mar 2009 due to a system problem)

ACIS-S and HRC Celestial Location Monitoring
The following plots are the difference between coordinates obtained from Chandra observations and those obtained from existing catalogs vs time in day of mission. The following steps are taken to generate these plots

* all observations with grating are selected
* even if the observation is not grating one, if it is a known point source, it is added to the list.
* observed ra, jan, target ra, jan, nominal ra, jan and a ratio of a target elliptical to psf (psfratio ) are extracted from src fits files.
* the observations with psfratio smaller than 4 are selected
* the differences between observed coordinates and targeted coordinates (if not available nominal coordinates) are computed
* if the differences are larger than 6 arcsec, the points are dropped





The large dispersion around DOM ~ 2400 (Jan 2005) are all due to none grating Capella observations. Many observations are off-axis observations (e.g., obsid 6558).

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).
