ASTRA Spectrophotometer: Reduction and Flux Calibrations

Abstract

The ASTRA Cassegrain Spectrophotometer and its automated 0.5-m telescope at Fairborn Observatory in Arizona will produce a large quantity of high precision stellar flux distributions. A separate paper (Adelman et al. 2007) presented a review of the design criteria for the system and an overview of its operation. This paper discusses the techniques used in the data reduction to final flux calibrations.
