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 and October 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: -117.99      std dev: 0.92
                 mean width:    0.52 days std dev: 0.41 
  

  
  
  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.

• 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.

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.
  We have selected only calibration observations of Capella, HR1099, and Sigma Gem.
  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).

SIM

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 two lines separated before and after (Days of Mission)= 1400 (May 21, 2003). The unit of slopes are mm per day or degree per day.

The sudden shift around DOM = 1400 was due to fid light drift (see a memo by Aldcroft fiducial light drfit). 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





SIM Motor Temperature
We track the SIM Translation Drive Motor Temperature using msid 3TRMTRAT. Below are plots for the entire mission showing temperature changes during each translation. Solid lines indicate the start temperatures (blue) and stop temperatures (red) smoothed by a factor of 100. Also plotted is spacecraft pitch angle (pt_suncent_ang) for reference. We explore the relationship between delta T and attitude and delta T vs. move distance.
