Corrects rawX & rawY as obtained from the telemetry for windowing and pre-scan, such that they are consistent with the convention used within the SAS, where rawX & rawY start counting from 1 for the first physical pixel on the CCD. Consequently pre-scan pixels have values of . Note that nominally the commanding will be such that the first physical bin on the CCD has coordinates (0,0) in the telemetry. ...
