    keyword=scaler & trigger notes

    I moved bcm u3 from the 7th scaler channel of the
    normalization scaler, to make room for T7. So, u3 is
    now in the 17th channel. I took care to move the fanout
    which people had put in for bigbite.
    The scaler.map file was updated in ~adaq/e04007/scaler
    and subdirectories there, as well as in ~a-onl/scripts.

    Here are the trigger definitions and locations in L-HRS scalers:

    trigger .... channel ... definition

    1 ....... 1 ....... bigbite E plane
    2 ....... 2 ....... bigbite dE plane
    3 ....... 3 ....... L-HRS S1.and.S2 (as for 10 years)
    4 ....... 4 ....... L-HRS efficiency (2 out of 3)
    5 ....... 5 ....... T1.and.T7 (but initially T1.and.T3, see note A)
    6 ....... 6 ....... T2.and.T7 (but initially T2.and.T3, see note A)
    7 ....... 7 ....... (middle 2 paddles of S1).and.S2
    8 ....... 8 ....... 1024 Hz pulser (aka clock)

    Note A: Inital definitions of T5,T6 will exist during a calibration
    phase, then switch to using T7 instead of T3.
