CCDS and WET: where are we and where are we going.

Abstract (from CDS):

An overview of the detector requirements for WET photometry is given, including discussion of why CCD usage has not been attractive for WET until comparatively recently. Initial CCD usage by WET is described along with a comparison of results from CCD photometry programs applied to the same data. It was found that a CCD on a 0.75 m telescope provided data which were almost as good as a photomultiplier tube results on a 1.9 m telescope. Aperture photometry was generally found to be in agreement with theoretical expectation, as well as being more precise than point spread function fitting. This latter result is surprising and not understood, though it is possible that coding problems are responsible.
