Configuration/Radiation Overview for November 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 Aug 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.

  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 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 between Sept and Oct was re-calibrated, and the data points are corrected accordingly.

  
  
  
• Focal Plane Temperature

    
         The Mean (max) FPT: -117.99      std dev: 1.11
                 mean width:    0.41 days std dev: 0.26 
  

  
  
  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.

  

• Bad Pixels
  

  The plots below were generated with a new warm pixel finding script. Please see Acis Bad Pixel Page for details.

  Back Side CCD (CCD5)
  

• 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.
  
  

  Name	Low (keV)	High(KeV)	Description
  SSoft	0.00	0.50	Super soft photons
  Soft	0.50	1.00	Soft photons
  Med	1.00	3.00	Moderate energy photons
  Hard	3.00	5.00	Hard Photons
  Harder	5.00	10.00	Very Hard photons
  Hardest	10.00		Beyond 10 keV

  
  
  
  
  

  The following three plots show trends of SIB from year 2000. CCDs shown here are CCD3, CCD5, and CCD7. Fitted lines are linear fit after eliminating extreme outliers. For >10 keV plots, 2 lines are fit. One is with a 13 keV filter, and another without.

• ACIS Histogram Mode Trends
  

  We collected data from acis histogram mode data, and created trend plots of peak portions and peak widths against time (DOM). The peaks were estimated by fitting a simple Gaussian on three peaks (Al, Ti, and Mn), and the widths were estimated by a width at the half max from the peak.

  All histogram data are taken under TIMED and GRADED_HIST mode, SIM position is at an external calibration source position, the focal temperature is around -119.7 C, and parameter settings in aciselec, acistemp are set to about same for all.

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.

  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.

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).
