    After rolling the L-arm spectrometer back in place, we
    reconnected the cables and adjusted timing. Note: T0
    changed, need recalibration. The coincidence window width
    should be about 105 nsec (95 nsec width on R-arm, 20 nsec
    width after adjustment from L-arm minus a minimum overlap
    of 5 nsec on each side). It would be wise to throw out all but
    the middle 80 nsec of this range, due to retiming window effects.
    Only one trigger setting is possible, as evident when you run ``trigsetup''.
    T2 (R-arm) uses Cerenkov, T4 (L-arm) is ``or'' of S1,S2.
    Regarding new trigger 6 (something from the calorimeter): We
    did NOT plug it into scalers. This could be done with a cost of 14 nsec
    delay of trigger due to fanout + cabling, but it was decided this extra
    delay was not worth it. I guess its a test trigger that will normally be off.
    Remember that any trigger not scaled can harm normalization (don't care ?).
    Bottom line, we're ready to run.
