WFC3 Cycle 22 Proposal 14007: UVIS Gain
Abstract
Herein we present the UVIS Cycle 22 gain results from for each quadrant using internal unbinned, 2x2 binned, and 3x3 binned flat field data with nominal gain setting (1.5 e-/DN). This report includes two epochs of data, including the previously reported one (Gunning, 2015) from Cycle 22 December 2014 and the new and unreported one from Cycle 22 June 2015. The June 2015 epoch of data has unbinned gain measurements of 1.57, 1.56, 1.59, and 1.57 e-/DN for quadrants A, B, C, and D, respectively. For the data from all the epochs covered in this report, the gain measurements are the same as or within 1-2% of previous values from TV3 through Cycle 22 and thus they remain stable.
