WFC3 Near-IR Channel: PSF and Plate Scale Study

Abstract

This report focuses on the PSF properties and plate scale optimization for the Near-IR channel of WFC3. We discuss how various effects lead to the final observed PSF in NICMOS Camera 2 and suggest apodization of the cold stop as a possible way to improve contrast for the Near-IR channel of WFC3. We derive a model for the pixel response of the NICMOS arrays… (More)
