Abstract:

Photometric monitoring observations of a white dwarf standard (GRW+70D5824) have been used to update the contamination rates for WFPC2 UV filters. Observations from April 1994 through May 2002 were used in the analysis. In general, the contamination rates have declined by roughly 50% for most of the filters during this period. Least-squares fits have been made to the data to allow observers to remove the effects of contamination in their WFPC2 observations.
