keyword=L-HRS S1 and S2 SignalsFigure 1 and 2 show the S1 and S2 ADC pedestal subtracted spectra
after adjusting the HVs to align the peak 1200 channels above the
pedestal.
For the S2-R6 PMT, the pedestal appeared to be noisy before HV
adjustments were made. After the HV adjustment,which was a ~ 10%
decrease, the nosiy events below the pedestal are gone.
