    keyword=a tiny bgr for dP=+20%

    During the dipole scan, we note that even with +20% detune there is
    a nonzero background.
    Fig 1 is for counting mode, one sees a tiny 3.5 Hz enhancement above
    beam off.
    Fig 2 is for integrating mode (run 5659). Max bcm1 is 50 uA.
    Left arm sees a tiny background that tracks with beam. BTW, the
    pedestals might need adjustment. Meanwhile R-arm (which is off) is
    just pedestal.
