Current: A percent of each xChan Detector current is subtracted, before any
material calibration, tooling factors, etc. have been calculated. The advantage
of this method is that a change in the xChan calibration factors does not impact
the amount of xChan compensation.
Rate: A percent of each xChan Detector rate is subtracted, after material
calibration, tooling factors, etc. have been calculated. This method allows
recalibration of an xChan to alter the amount of xChan compensation.
