    During the access, we made sure signals are plugged into an 1877
    for both T1 and T3. Actually they already were. Both are in roc4
    slot 13, and T1 is in chan 49, T3 in 50. We should see a peak here
    corresponding to coincidences.

    We also decided, based on the comparison of pulser and beam data,
    that the T3 was delayed about 64 nsec too much. So we took this
    out of Ldelay1 (also for T4) and added it back in for the L1A.
    We verified that retiming was still ok.

    To make the edtmsetup form coincidences we took out 80 nsec of
    delay from it.

    We've asked for the beam. When we get the beam we may adjust
    delays remotely to get good "ctime" measurements.
