    keyword=BB MWDC HV scan

    We made a quick HV scan to check the efficiency of
    the BBs MWDC at "low HVs"

    MWDC_Threshold_front = 4V
    MWDC_Threshold_back = 5V

    Run # | HV | N-events
    -------------------------------
    2207 | 1500 | 1.1M
    2208 | 1450 | 1.0M
    2209 | 1400 | JUNK!!!
    2210 | 1400 | 1.0M
    2211 | 1350 | 1.0M

    Run #2212 is again the production run with HVs set back
    to 1550V.
