WF/PC INSTRUMENT SCIENCE REPORT 91-07:
Analysis of Stellar Monitor Proposal #3173
By Christine E. Ritchie
July, 1991
Abstract excerpted from the report:
WFC and PC observations of BD+75D325 have been taken for 3 consecutive months through the Stellar Monitor proposal 3173. Aperture photometry shows stable sensitivities to a few percent in filters F439W, F555W, and F785LP. F336W is stable to 5-10 percent and has returned to the originally observed sensitivity since the Flash decontamination on July 5. The sensitivity is not stable in the UV, but has increased since the Flash decontamination.
