    This entry is a followup to: 81659

    keyword=trigger latch pattern

    Below is a plot regarding the newly installed trigger latch pattern (i.e. new for RCS,
    it was there in other experiments). The X axis is the bit pattern in the TDC that
    receives the 8 triggers after prescaling from the trigger supervisor. The Y axis is
    the CODA assigned event type, which you see in the event header. One can see a
    diagonal, like (1,1) and (3,3) and (6,6), etc. Most events are evtype 5 which are often
    accompanied by bits 1, 3, 5, and 7 as expected. Event type is not mislabeled (at
    least not badly) for this run 2034, but one might want to check with other ps factors.
    There is some dirt. It might be cleaned with cuts on time since its a 2 usec
    window for this TDC, I think
    It seems the channels are 64-76, in slot 11, not what was said in halog 81659.
