keyword=Gas Cerenkov (LHRS) HVI have adjusted the LHRS gas Cerenkov HV to align the single
photoelectron peak to about channel 150 above the pedestal. Channels
0,1,3,4,5,6,8, and 9 were changed. There is not much signal in
channel 9 with cosmics. It appeared with beam that the HV was too
high so I have decreased the HV for this channel. However, it needs
to be rechecked with beam.
