    This entry is a followup to: 116038

    keyword=RICH event lengths

    For a run with huge event sizes like 1893 the
    script rich_online.C seems to take about an hour
    and when the canvas did finally pop up the mean
    value was "zero" since presumably all 794 entries
    were above the upper limit of the histogram (1000).
    I guess the RICH code is doing much more than just
    this histogram, hence the 1 hour turnaround.
    So, in order to simply check the RICH crate event
    sizes I added 2 histograms to detectorL.cfg.

    Fig 1 indicates what is "normal" (run 1894) -- avg lengths ~60.
    Fig 2 indicates "abnormal" (run 1893) -- length ~2500.

    It is important to monitor the CODA event size !!
    And we need to fix the underlying problem too.
