    keyword=BPM 8 and 12 into ROC13

    I plugged in the cables for BPM 8 and 12.
    Fig 1. shows raw signals on the 8 ADC channels.
    Something exists and does not saturate ADC.
    Fig 2. shows an EXTREMELY NAIVE calculation
    of positions. Calibration is basically UNKNOWN and I
    have no clue if the signals make sense. (I used the
    same calibration as BPM 3B, for fun.) To test this
    we would need to: 1) Do a pedestal run; and 2) See
    how position of CODA correlates to EPICS. I.e. we
    have to calibrate similarly to "spot".
