Instrument Science Report WFC3 2008-19 WFC3 TV2 Testing: IR Intrapixel sensitivity P. McCullough August 26, 2008 ABS TRACT We derive an approximate intrapixel sensitivity variation (IPSV) of the IR-1 detector of WFC3 from ground-test imagery. ... A lab test designed to study IPSV might illuminate the detector from a fiber optic cable, the tip of which can be much smaller than a pixel, and by raster scanning, one can map the IPSV with very fine sub-pixel precision. ...
