  • The Mean 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.
    

  • Bad Pixels

    Warm pixels consistently showed a bias level more than 5 sigma away the chip's mean level during this period.

    

    Hot Pixels - No new hot pixels observed this month.
    Previously reported:
    Pixel 1022,166 of Quad 4 CCD 5. We define a hot pixel as a pixel with the count rate 1000 counts above the average
