    keyword=trigger mods -- coinc window

    Reduced the coincidence window by 30 nsec, by adjusting
    the width of the H-arm trigger signal 30 nsec. The e-arm
    signal remains same. A diagram showing the signal widths
    and overlap for infinite momentum is in paper logbook 2, page 134.
    The h_delay_1 module was increased 16 nsec, and h_delay_2
    decreased 8 nsec for all momentum. It is asymmetric to
    accomodate the constraints at retiming module. According to
    our previous measurements when Calarco was here, I can predict
    we will not get the doubled self-timing peaks again. But it should
    be watched anyway.
