Quick pedestal analysis.Summary: 1-2 dead PMTs 2 bad signals (wide pedestals) 2 missing, DB problem? The rest are good enough to run...
155, 255 -- no counts in histo, database problem? 56, 259 -- very wide pedestal 149 -- very sharp (intrisic) pedestal, confirmed no signal from PMT 159 -- sharp ped, PMT might be dead too 167, 229, 240 -- ped good, but at either high or low ADC value. DC offset?
