    keyword=Triggers for Transversity

    I completed setting up the triggers. The only thing needs to be checked
    is to see if T4 is aligned with all other triggers. I'll do it tomorrow
    morning since Hall will be closed soon.

    Here are the triggers for the experiment...

    T1 = BigBite Total shower
    T2 = BigBite Total shower + Cerenkov overlap
    T3 = L-HRS Singles (S1.and.S2)
    T4 = L-HRS Efficiency (S1.or.S2)
    T5 = T1.AND.T3 (BigBite LHRS Coincidence)
    T6 = BigBite Total shower 2nd trigger(different threshold than T1)
    T7 = BigBite Cerenkov only
    T8 = 1024 Hz pulser
    T9 = BigBite cosmics(front-back)
    T10 = BigBite cosmics(top-down)

    Note : Triggers T9 and T10 are for cosmic checks for the BigBite and will
    be used only when there is no beam for extended period of time(~few hours)
