    keyword=T3 timing HRS S1 S2m

    S1 signal for T3 trigger plugged into Fastbus crate 4 slot 12 ch 14
    (counting from 0)
    variable S1nT3v2
    S2m signal for T3 trigger plugged int ch 15
    variable S2nT3v2

    Run 7409 TDC spectrum is 0.5 ns/count
    Contrary to my expectations from Cosmic rays, S2m signal is
    still about 50 ns early. This means that T3 timing is from
    S1 NOT S2
