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.
