    keyword=Failure of central crystal calibration

    In some recent Compton production runs (20061, 63) the histogram
    labelled "Central Crystal Calibration" has failed, in the
    sense that it looks very strange. This makes me worry
    that our setup is not quite right.
    On the other hand, run 20064 looks normal, though
    nothing was changed. It would be nice to know what causes
    this instability.

    Otherwise the histograms seem ok.
