Abstract

A measurement program designed to investigate the variations in sensitivity of focal plane array son a sub-pixel scale has produced such information for two devices: a two-phase front-illuminated CCD and a three-phase back-illuminated CCD. The effect of a non-uniform pixel response on a aperture photometry has been previously analyzed for a front-illuminated CCD. This paper presents results regarding the photometric errors to be expected for a back-illuminated CCD and astrometric errors for both devices. The uncertainty introduced in both measurements, when using under sampled data, is significant.
