WFPC2 Technical Instrument Report 97-07:
WFPC2 Internal Monitoring for SM97
-Mutchler and Stiavelli
The goal of SMOV proposal 7022 was to verify that there was no change in basic WFPC2 instrument health and internal calibrations. A variety of internal exposures were obtained in order to provide a monitor of the integrity of the CCD camera electronics in both bays (gain 7 and gain 15), a test for quantum efficiency in the CCDs, and an internal check on the alignment of the WFPC2 optical chain. Analysis of the data from program 7022 shows that the servicing mission caused no significant changes to these parameters.
