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
Otherwise the histograms seem ok.
