    IHWP = OUT
    RHWP = 6435
    Set IA to 4.85 (Zero Point Qa from Parity run #1610)
    INJ BPMs remain the same. Didn't change any cabling.

    IT = 13300
    RD = 0
    OS = 0 (1)
    IA Feedback ON

    From these scans, it appears (roughly, assuming a linear relation) that
    d(IA)/d(pztX) = 0.906
    d(IA)/d(pztY) = 0.905
    Perhaps I didn't need to be so shy with PZT-X.

    Now an oversampling run. IA Feedback OFF.
    PZT X = PZT Y = 5
    IA = 4.92

    IT = 1000
    RD = 0
    OS = 12 (13)

    CH DAQ ADCs set to HI-Gain
    (pedestals will need to be re-calibrated for HI-gain)

         Run #'s            PZT            IA          HRS #'s

    Returned DAQs to Before-PZTscan state:
    CH DAQ ADCs set to LO-Gain, ADC 0 and 4 set to HI-Gain

    RD = 0
    OS = 0 (1)
    IA Feedback ON.
