    keyword=BPM/Harp calibration results

    By looking at the harp calibration run 1250~1263, I calibrated BPMs as:

    bpma -7.91e-4 5.62e-4 -7.516 2105 2104 2098 2098 1.0 1.0 0.01887 1.10 1.07
    1.1 1.35
    bpmb 5.75e-4 -0.05e-4 -2.378 2090 2085 2085 2086 1.0 1.0 0.01887 0.98 0.97
    1.1 1.35

    The attached comparison between harp and bpm readout is what I got after calibration. Each star represents a run.

    For reference I listed what Bodo Reitz got for e97111 and what the previous value was:

    e97111:
