An On Orbit Determination of Point Spread Functions for the Interface Region Imaging Spectrograph (IRIS)
Abstract
IRIS is a small explorer spacecraft that observes the solar photosphere, chromosphere, transition region, and corona using a combination of slit based spectrograph and slit-jaw imagers. The hard edge terminus of the May 09, 2016 Mercury transit observed by IRIS is used to measure on-orbit point spread functions (PSFs) for the near ultra-violet (NUV) and far ultra-violet (FUV) spectrograph channels. The contribution of the measured PSFs on spectrograph resolution is investigated.
