    keyword=Coincidence time changed in two run periods

    I happened to check the coincident time for the January run period and the March run period (due to some problem in my cuts). I found a significant change . The first histo is for Jan-run-period coincident time (centered about 81 ns) and the second histo is the same for March-run-period (centered about 99 ns) . I don't see any reason for this change except Rob could have made any changes in the detectors themselves (in S1, S2 planes of any HRSs).
