    keyword=Kaon Coincidence time

    Looking at different runs, I see that the position of the coincidence-time peaks changes (my feeling is that it is drifting)!!!
    For examples:

    run 2780 (100 microA, beginning of Be production): pion peak at
    150.0 ns, kaon at 152.5 ns

    run 2980 (140 microA): pion peak at 151.7 ns, kaon at 153.8 ns

    run 2992 (120 microA): pion peak at 151.1 ns, kaon at 153.5 ns

    We were using a kaon window around 152.1 ns (it was good on Carbon, at least for the beginning), I changed the time window to match the present condition (run 2992) and the scale on the physics replay, so now peak movements can be monitored on line
    (I will check and investigate better later).
