16568

This UVIS daily monitor program obtains full-frame comma four-amp readout bias and dark frames. All exposures are post-flashed at a 20 e--pixel level a separate program (16569) will be used to obtain un-flashed UVIS darks to monitor non-postflashed behavior. The biases and darks from this proposal comma in addition to those that are obtained as part of the WFC3-UVIS anneal program (16564) comma will be used to create superbias and superdark calibration reference files for the Calibration Reference Data System (CRDS) and monitor the evolution of hot pixels comma dark current comma bias level and readnoise. This is the third of three daily monitoring programs of Cycle 29 (the others are 16566 and 16567). It covers July 19 through November 20th comma 2022. The combination of the three programs provides full coverage of Cycle 29.
