    keyword=EDTM system fixup

    Bodo and I realized that the reason the scaler measurement of EDT
    didn't make sense was that we are pulsing 8 channels, but only 6 are
    used by scintillators. The extra 2 can overlap with trigger, leading to
    a falsely "negative" deadtime. The best solution would be to disable the
    extra 2 channels, or to form the "or" of only the 6 that are used. We didn't
    have time to do this during this access, so we simply send all 8 channels
    through the trigger now. The EDT measured in scalers will be approx
    correct now, except for a small correction due to the 2 channels having
    no scintillator signals. Meanwhile the event analysis should work, and
    we can now compare with scalers.
