The remaining question is: why the number of ph.e. is low ?
Need just simple analysis: please, focus on large angle side PMTs.
Plot 1-d histograms for the events vs X and Y with best
selection of electrons by other means (time, preshower, ...).
Make these hists for the small amplitudes in ADC and
separately for the events with large amplitudes.
If we observed difference in coordinate distributions it
will indicate that UV photons are lost due to mirror quality.
If the differences are small than we likely have duty gas.
