One glance at the filter energy plot shows a substantial chunk of events missing for the all the tests, for example at lower energy for AllGamma (below left). The effect is the same for also present for B1-1-2 in GRv15r46p1. Note that the system test filter energy plot has no cuts applied and the job options are set to pass all events.
On the bright side, we are removing background events with a shocking efficiency. Looking into a discrepancy between the system test merit file and this plot for the BackGndMixDC2 test. There should be a few hundred events in it.
