Instrument Science Report WFC3 2005-14 Results of WFC3 Thermal Vacuum Testing: IR Channel Gain B. Hilbert April 11, 2005 ABSTRACT Thermal vacuum testing in September - October of 2004 provided the fist opportunity to measure the gain of FPA64 since its integration into the instrument. Gain values derived from this data are between 2.43 e-/ADU and 2.50 e-/ADU, roughly 5% lower than those calculated for FPA64 at the Detector Characterization Lab (DCL). ... Gain values for each quadrant of FPA64. ...
