Description & Contents

Abstract

We report on the results of a test program to explore the potential scientific benefit of using non-standard gain settings in NICMOS observations. While this capability had originally been included in the NICMOS design, it has never been used on orbit. We present our analysis of the test data, discuss the potential scientific benefits, and outline the necessary modifications to planning, implementation, and pipeline calibration of NICMOS data taken with non-standard gain settings.
