Scientific paper

We propose to catalog fluxes and derive sizes and albedos for all asteroids with small positional uncertainties that appear serendipitously in publicly available IRAC and MIPS archive data. We will make at least 25,000 independent measurements. Our results will help extend the small end of the asteroid size frequency distribution of main belt and Jupiter Trojan asteroids; reveal compositional gradients and remove compositional degeneracies; look for common properties among asteroid families; and serve as a fundamental database of asteroid properties for the coming decades. The SSC asteroid identification tools are inadequate for this task and furthermore provide no analysis of asteroid data. We have developed and demonstrate a pilot automated pipeline capable of extracting asteroid detections from IRAC and MIPS imaging data products and generating a first order catalog of fluxes, albedos, and diameters. This pipeline will be applied to the entire publicly accessible Spitzer imaging archive. The results will be published in refereed papers and in NASA's peer-reviewed Planetary Data System.
