• The Mean Detrended CTI

  From this month, 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

  
  
  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. A independent variable is date, and a dependent variable is CTI.

• Focal Plane Temperature

    
         The Mean (max) FPT: -117.76      std dev: 1.35
                 mean width:    0.41 days std dev: 0.19 
  

  
  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 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 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.

• 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.

Science Instrument Positional Change Monitoring

ACIS-S and HRC Celestial Location Monitoring
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

Fid Light Drfit

As mentioned in Aldcroft's memo, fid lights drift with time. We plotted fid light trends (see fid light drift page).

Example plots for I-1 CCD Fid ID 1 and 7 are shown here. There are two fid light trends on I-1. The drift shown here is in the direction of acent J in unit of pixel.

The top plot shows both fid light trends, following 2 panels show a detail trend of each fid light. The slope of the trend and an average TSC position are listed.

Sim Shift and Twist

We also monitor shifts and a twist of SIM. Y and z direction shifts (dy and dz) and twist (dtheta) are directly taken from pcaf*_osol1.fits files, and plotted against time. As of the end of September 2004, there is no shifts or twist are observed.
