keyword=Do not cut on only g.evtyp!!The physics events are coming in with the CODA event types 2, 3 and 12 if multiple trigger-types are overlapping. The figure below shows how they go into the "D.bit3" coincidence time plot. The moral of the story: do NOT place a cut at the RawDecode level that g.evtyp==2 or 3 (or even 12) since this CODA event-type is not a solidly-defined type (as Bob has warned us).
Given that the data we have now is ONLY really T2 and T3 triggers, with
the pulser T7 trigger thrown in, there is no benefit to cut on the
event-type in the analyzer's analysis of the run. It will be removed from
the cuts.def file.
