4.1.1 CCD Subassembly Calibration Measurements

This section describes the objectives, measurements, and required measurement accuracies for ACIS CCD subassembly calibration performed at the MIT Center for Space Research. These calibration measurements have been performed on each flight candidate detector before it was assembled into a flight focal plane. Only detectors which met the requirements established in the ACIS CCD Screening plan (ACIS memo PS-77) were calibrated.
