From this month, we report CTIs with a refined data definition. CTIs were computed for the data taken during the focal plane temperature < -119.7 C, and the integration time longer than 7,000 sec. This eliminates a CTI temperature dependency, and the shows CTI degradation with time much more cleanly. 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 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.

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