Abstract

We describe recent orbital test data acquired with the COSTAR/Faint Object Spectrograph (FOS) on the Hubble Space Telescope (HST). These data exhibit possible internal thruput deficit and scattering features in the FOS. We then describe some data from laboratory measurements of COSTAR optical components carried out at Ball Aerospace Corporation and NASA/Goddard Space Flight Center, which we initially thought might bear on some of the orbital test data. We use next, a theoretical model to simulate some of the HST/COSTAR/FOS imaging and spectral performance. We apply the model to the current data to assist in evaluating COSTAR iamging performance, to attempt to isolate the origin of the thruput deficit and scattering features. The results of these studies will permit a better understanding of the limits of HST performance and permit development of optimal strategies for performing spatially resolved spectroscopy in the FOS scientific observing program.
