    keyword=Helicity pickup for pedestal run 4462

    Here I have plotted the differences for the individual wires of the bpms
    during run 4462 which is a pedestal run. The injector bpm wire signals
    are clock divided and the hall bpms are DAC-noise subtracted.

    The differences in the hall are zero within 1 or 2 sigma. The injector
    differences aren't zero unless you go to 4 or 5 sigma.
