... Analysis of the UVIS03 data show that the gain ratios, relative to the nominal 1.5 , are 1.01-1.04, 2.09-2.15, and 4.28-4.39 at a detector temperature of -82C. A check of the absolute gain of the nominal 1.5 setting was performed using flatfields from the linearity (UVIS05) test; gains were measured at 1.53, 1.52, 1.56, and 1.55, with errors 0.01 , for quadrants A,B,C, and D. Introduction The purpose of the ... Gain ratios for the four quadrants, relative to gain 1.5. ...
