ACIS Gain Plots

ACIS gains were computed with following steps (see C. Grant memo:ACIS Gain @ -120 C for more discussion ):

The x axis is in year, and y axis is in ADU/eV for gain plots, and in ADU for offset plots. The slopes are either ADU/eV per year, or ADU per year. Click a plot to enlange it.
