    keyword=charge asymmetry confusion

    We had some beam (for Compton tuning) with BeO target.

    We took data at 5muA, and then ran beam charge asymmetry analysis
    on the run; qasy gave -410 ppm (deltaQ=80) but the parity asymmetry
    gave -638 ppm (BCM1) and -706 ppm (BCM2). We do a timestamp
    of the asymmetry with -410 ppm - but now we wonder if the feedback is
    on at all, and is it working? We note that the beam 1/2 wave plate is
    IN, so that the slope is opposite to that in log entry 62548 - so did MCC
    update the slope? Is the feedback program running at MCC?

    Also, the timestamp is off by 2 hours on that GUI... Why?

    Separate aside - we plugged back in the DAQ sync cable before these
    runs, so we are back to the Parity DAQ controlling the other 2 DAQs...
