Configuration/Radiation Overview for April 2005

ACIS

• ACIS DOSE registered-photon-map

  We updated ACIS cumulative dose map from this month. The steps we took to compute a new 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 Jul 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.

  Please check more detail plots at Telemetered Photon Dose Trend page.

• The Mean Detrended CTI

  We report CTIs with a refined data definition. CTIs were computed for the temperature dependency corrected data. Please see new 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: -116.68      std dev: 1.87
                 mean width:    0.43 days std dev: 0.31 
  

  
  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.
  

• Bad Pixels
  

  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.

DOSE of central 4K pore-pairs


From this month, we trend 10th brightest data points instead of the maximum. This makes the maximum trend values to be about 20% lower than the previous months.

Gratings

• 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.
  For this month, we has selected only calibration observations of Capella and HR1099.
  See MIT technotes for a parallel analysis.

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).
