    Today we did the following for the trigger:
    1. Checked that the pulser flag is registered with
    good efficiency in the events. See end-of-run comment
    for run 2896 where this was proven to be ok.
    2. Added 16 nsec more delay to Aerogel so that it
    nicely encompasses the S-Ray signal at MLU input.
    These two inputs are patched through to the counting
    room, to look on scope. The patches are in rack
    CH01B04 (middle room ), near the bottom (a label
    says "50 ohm to 1H75B03 in hall A"), and are
    number 11 = S-ray, num 9 = Aerogel.
    3. I also tried to look at TDC for Aerogel, but unfortunately
    it reads 4095 both with and without beam; probably because
    the signal is so wide and overlaps the end-of-range of TDC.
