    keyword=A1 and A2 summed ADC spectra

    A1 and A2 summed ADC spectra.

    A1 has a long, funny tail, making me think that the database is not very good. On A2, the average of "15" is very low, so something is probably NOT correct in that database. Additionally, at least one PMT on A2 is not giving a good spectra (ADC 10 is empty)

    Also, I set each ADC to appear to have the single PE peak at channel 100 in the corrected spectra. As these are really poissonian distributions, the real single PE peak is at channel 80, not 100 meaning each of the below spectra really has a PE every 80 channels and not 100.
