-/// there is no structure); or the overscan may be fit perpendicular to the read direction (usually the
-/// columns) with a particular functional form; or a single value may be subtracted for each read/scan without
-/// fitting (if the structure defies characterisation).  In any case, statistics are required to reduce
-/// multiple values to a single value (either for the scan, or for the entire overscan regions).
