Instrument Science Report WFC3 2009-07 Overview of the WFC3 Cycle 17 Detector Monitoring Campaign

Abstract

During the Hubble Space Telescope’s Cycle 17—nominally from August 2009 to October 2010— eleven calibration programs will be executed to assess the stability of the detector response. Six core programs will monitor changes in flat fields, dark current, bias, and gain in both the UVIS and the IR channels. Five additional programs will monitor specific detector effects of interest to observers: contamination, hot pixels, charge-transfer efficiency, and quantum efficiency hysteresis in the UVIS channel, and persistence in the IR channel
