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 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 display a max dose trend plot corrected for events that "pile-up" in the center of the taps due to bad position information.
