IR Flat Field Stability Monitor
Abstract
This is a continuation of programs 11433 {SMOV} and 11915 {Cy 17}. In this program, we will study the stability and structure of the IR channel flat field images through all filter elements in the WFC3-IR channel. Flats will be monitored, i.e. to capture any temporal trends in the flat fields, and delta flats produced. High signal observations will provide a map of the pixel-to-pixel flat field structure, as well as identify the positions of any dust particles.This version contains monthly monitoring of all broad-band filters and one full set of all filters at the end of the cycle. A total of 54 internal orbits are used.
