Moving on to Pass7, the ACD analysis has be modified a fair amount. I rebuilt GR v17r35p10 and generated roughly the same number of signal and background events (again using Eric allGamma.txt and background.txt scripts).
The efficiency for the prefilters is effectively the same (13% Irreducibles, 47% AcdEngCut, 2.2% TkrCalCore) leaving a total of 1.3% of the bkg and XX% of the gamma-ray events.
