    Two nominal runs were taken because NMR measurement was done after first run,
    so there was no beam for ~20 min. I thought it would be a good idea to do another
    nominal run so all points of PZT scan were taken at the same time. Run 1659 ended
    because beam suppressed in order to put in electron detector for Compton.

    Now, I will take an oversampling run with the parity and injector DAQs.
    IA feedback off
    IA = 5.03
    IT = 1000
    RD = 0
    OS = 12 (13)
    ADCs in High gain. (Pedestals need to be calibrated)

    Parity Run......Injector Run......R/L arm runs.....PZT(x,y)....IA init....IA final
    1666....................5219................1703/20703..........(5,5)..........5.03.......5.03

    Settings back to nominal. IA Feedback on.
    IT = 13300
    RD = 0
    OS = 0 (1)
    ADCs in low gain (0 and 4 in High gain).
    Parity run 1667 taken to verify that feedback is still working.
