    keyword=HV Changes for RHRS

    Figures 1 and 2 show the HV settings for the RHRS detectors. I
    increased the HV for preshower channel 41 and shower channel 56 (see
    Halog entry # 210382). This should be improved but will need be to
    checked with beam.

    I also adjusted the HV for the gas Cerenkov channels: 0,1,2,4,6, and
    8 to align the single photoelectron peak. The peak was a bit low
    compared to the odd channels. They should all be close to 100
    channels above the pedestal now.
