- The Mean CTI
Note: Temperature data selection changed. 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 Squeegy (average of 4 nodes per chip). CTI's are computed for Mn K aplha, 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.

- Bad Pixel Candidates
Warm Pixels - new warm pixels observed this month are marked with "*" (due to change in warm pixel definition) The following front-illuminated pixels consistently showed a bias level more than 5 sigma away the chip's mean level during this period (Note:a definition of a warm pixel was changed to match with that of MIT).
