WFC3/UVIS 2.0
Abstract
WFC3 UVIS data processing pipeline has been improved to provide better precision by implementing chip dependent photometry and cte corrections. The two UVIS CCDs have different characteristics, different QE and different wavelength dependent response functions. Therefore, to improve the photometric precision, new flat fields, zero points, encircled energy curves and aperture corrections were generated. In this presentation we describe these changes, and their effects on data analysis, including using AstroDrizzle. CTE corrections are presented by S. Baggett at this meeting.
