• 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: -119.00      std dev: 1.16
                 mean width:    0.54 days std dev: 0.29 
  

  
  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 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.

PCAD

ACA Trending
Fid LIght Drift We plotted here fid light trends on each CCD. There are usually two fid light trends on each CCD. The drift shown here is in the direction of acent J in unit of pixel.
The drift is about -0.0007 pixels per day or 7 arcsec over the course of the mission thus far.

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).
