• The Mean Detrended CTI

  Observations with cold radiator temperature deviation larger than 0.5 C
  from the nominal value of -127.92905 C are dropped (after DOM 200).
  
  
  Mean CTI observed when FPT~ -119 C and no testing modes (Squeegy, cuckoo, etc.) (average of 4 nodes per chip).
  CTI's are computed for Mn K alpha, and defined as slope/intercept x10^4 of row # vs ADU.
  Data file here
  

  
  
  CTI Slope (after DOM 200)

  
  CTI slopes were computed for data point after DOM 200 and inside of 1 sigma deviation.
  Using only data point in 1 sigma range, we drop high temperature observations, squeegy
  observations, and other outliers. A independent variable is date, and a dependent 
  variable is CTI.
  
  Note: Unit is cti/day from this month report.

  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.

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.
  
  
  

ACA Trending

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).


Sep 2003 Timing Plots       Entire Mission Timing Plots

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
* 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
