keyword=S2 ADC basically already matched
Shloka did fit the ADC spectra for the S2 scintillators based on the left HRS run we took a few
days ago (run 7480). Below are her results showing that as expected the ADC signals between
the various tubes are basically matched. I do not think we need to change the HV. Also the
pedestals shown here do match (pretty closely) the pedestals we had extracted with cosmic
data.
