Final Report: SUPER HI STAR Experiment.

Abstract

Numerical coadding of repeated scans of an attitude-stabilized rocket-launched cryogenic telescope has achieved the theoretical gain of N in signal-to-noise ratio. The 3 December 1975 flight of the telescope also demonstrated a sensitivity improvement nearly as large, resulting from the increased effective-integration time, while retaining the higher frequency response of the detectors to discriminate in favor of point sources. Several infrared sources in a 1.2 deg by 10 deg area around beta-Andromeda were measured at 11.0 and 19.6 micrometers, including two faint red galaxies (NGC 389 and NGC 393) and a number of unidentified objects.
