    keyword=No ADC signal for Cerenkov (LHRS)

    Figure 1 shows the left gas Cerenkov ADC spectra. The HVs were pretty
    low well below 2 kV. Run # 1269 is after we increased the HV to 2300
    V. I suspect the ADC cable might be unplugged. The TDCs do show
    signals. We also have T4 events for the left arm. Hence the scalers
    and TDCs do not appear affected.
