WF/PC Photometric Monitoring Results
By Christine E. Ritchie and John W. MacKenty
February, 1993
Abstract excerpted from report:
WF2 and PC6 observations of the photometric standard star BD+75D325 have been taken monthly since May 1991 for photometric monitoring of the WF/PC-1. This report contains the results from this program through the end of 1992. All filters below F785LP show decay in throughput sensitivity which has been restored periodically by scheduled (and unscheduled) decontaminations.
