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 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
  
  September 2005 points are miscorrected. The temperature is unknown due to the DEA reboot glitch, causing the focal plane temperature to be uncalibrated.

  
  
  
• Focal Plane Temperature

    
         The Mean (max) FPT: -117.11      std dev: 1.23
                 mean width:    0.68 days std dev: 0.40 
  

  
  
  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.
  
  

  Name	Low (keV)	Hight(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

  
  
  
  
  
  
  
• ACIS Rejected Events
  The links below are plots of stat1 quantities, showing on-board rejected events. The average EVTSENT, DROP_AMP, DROP_POS, DROP_GRD, THR_PIX, and maximum BERR_SUM obtained from L1 acis*stat1.fits files are plotted for each observation. CTI observations are plotted separately from regular science observations.
  
  Column definitions:
  • EVTSENT - number of events sent in data record
  • DROP_AMP - number of discarded events due to corrected amplitude
  • DROP_POS - number of discarded events due to CCD position
  • DROP_GRD - number of discarded events due to grade code
  • THR_PIX - number of pixels above respective threshold level
  • BERR_SUM - number of pixel bias errors so far in science run
  
  Note the half-life decay of the CTI source is clearly evidenced in the steady decline of EVTSENT.

  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.

  Gyro Bias Drift
  
  

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).
