    Entry number 324401

    keyword=Qsq runs, part 1

    Runs 27721 and 6838 with VDCs on.
    Pb/D tgt 3 for Qsq measurements.

    Mistake: Quartz HV too low (set for integ. mode).
    J. Wexler puts HV to 2000V.

    Runs 6839 and 6840 are good.
    Also runs 27722 and 27723.

    On L-HRS I see the upper and lower quartz detector,
    and on R-HRS I only see upper, yet it is not well
    separated from pedestal. And no lower quartz.
    Of course it could be due to software (?)
