Differences for the comparison with the previous release, GR v15r46p1, are in the filter energy as described below. The filter bits have changed and this has apparently caused more events to not have a filter energy assigned by the Onboard Filter? The difference in filter energy only appears for simulations and may be due to problems in simulating GEM bits. Update: the difference in the all event filter energy distribution is expected behavior. Events without a GEM bit no longer have a filter energy set.
Differences with respect to GR v15r45 include these and the shift in filter energy due to the cal peds and gains included in v15r46p1.
This is a candidate for L1Proc. The differences in the comparison with the preceding L1 Proc version, GR v15r40 are understood to be those discussed in GR v15r42, and the differences due to misinterpreting the new gamma filter in MC the new filter behavior for FSW B1-1-3.
Changes
- OnboardFilter, OnboardFilterTds, IExternal/obf - filter updates for FSW B1-1-3
- lsfData - fix handling for GammaFilterRsdV3

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 not 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.
