    keyword=BCM in End-of-Run File

    The charges that are listed in the end-of-run file are from the scaler
    BCM rates, which are then converted to charge via coefficients that are
    determined from the BCM calibration. Before the constant is applied,
    a BCM offset is subtracted. These offsets are determined for each BCM
    scaler reading and are determined from periods of time without beam.

    The scaler reading minus the offset results in a negative value when the
    scalers are not gated by the helicity-target spin signal.
