WF/PC INSTRUMENT SCIENCE REPORT 92-04:
Measles Contamination and Compensation with Delta Flat Fields
By John W. MacKenty and Sylvia Baggett
May, 1992
Abstract excerpted from the report:
The WF/PC-1 camera heads were decontaminated on Day 1992.034 (Feb 3), following a long period of continuous cold operation of the WF/PC-1 CCD detectors during which many GO/GTO sciences observations were obtained. The decontamination procedure restored UV transmission (temporarily), blue performance, and reduced the internal scattered light. It also made the expected small changes in the flat field structure but did not re-introduce QEH.
