    keyword=online DT estimate updated

    I've updated the online estimates displayed in DATAMON
    and in HALOG. The former is controlled by scdtime.c
    and the latter by halla_scaler_process.tcl.

    Offline the deadtime is trivial to calculate because you
    know how many triggers of each type were accepted.
    Online one must unfortunately correct for correlations
    because all you know is L1A and input trigger rates.
    So the assumptions are:
    Every T5 is a T1 and a T3
    Every T6 is a T2 and a T3
    Every T7 is a T3.

    Also, I modified ~/scripts/scaler.map to include all triggers
    (some were missing). And this needs to a different scaler.map
    file from the "official" one, so don't copy. See the scaler.map
    for why.
