This page describes the HV calibration of the eemc towers.
Run 6044054 was used to calculate gains from slopes
Input of this macro is the output from gainAverage.C. Output is summary files found below
3 plots on one canvas. # of PMT's which would have their HV changed, average HV change, absolute value of HV change
24 plots, 2 for each etabin, showing current gain in blue, and directly below, anticipated gain in red.
