• 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

  
  
  
• Focal Plane Temperature

    
         The Mean (max) FPT: -118.00      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.

  Front Side CCDs
  

  Back Side CCD (CCD5)
  

• 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.
  
  

  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 janay of the CTI source is clearly evidenced in the steady janline of EVTSENT.

ACA Trending
Fid Light Drift

Fid light positions on ACA drift with time. The drift trends of Fid light 6 with ACIS S configuration are shown below.

The top panel shows Fid light 5 drift in ACENT I (app. along with -Y axis), and the bottom panel shows that in ACENT J (app. along with Z axis). The unit is a pixel, and one pixel is approximately 5 arcsec. The slope listed at the top right corner is the change in a position per year (arcsec/yr). The vertical line on DOM = 1411 (June 1, 2003) indicates a transition date of use of IRU-1 to IRU-2.

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).
