I looked at a couple of runs from the left and right HRS to get an estimate for the percentage of good events per run. The attached plots show the individual cuts applied to each run. In each plot the red line shows the raw spectra while the blue line shows the applied cut. LHRS run 1895 (Cuts shown in figure 1) Number of Events in Run = 3435700 Number of Good Events = 2260296 Percentage of Good Events = 65.8% RHRS run 21019 (Cuts shown in figure 2) Number of Events in Run = 4880800 Number of Good Events = 3279113 Percentage of Good Events = 67.2%
