Behavioral model and simulator for the Multi-slit Optimized Spectrometer (MOS)

Abstract

The Multi-Slit Optimized Spectrometer (MOS) is a NASA funded Instrument Incubator Program (IIP) to advance an innovative dispersive spectrometer concept in support of the GEO-CAPE ocean science mission. As part of the instruments design and testing, we constructed a 'behavioral model' of the instrument's optical engine which allows an end-to-end simulation from input radiances to final product maps. Here we describe the model used for a rapid, but realistic, simulation of the MOS optical engine, and give illustrative examples of quantitatively tracking errors in the imaging chain from input radiances to bounds on final product errors.
