Polarimetry with the diffuse infrared background experiment aboard COBE

Abstract

This paper describes polarimetry of the Galactic plane and the zodiacal light, surveyed by the COBE Diffuse Infrared Background Experiment. Methods of analysis and the overall polarization characteristics of the diffuse sky are emphasized over interpretation. Results are illustrated by polarimetry at 2.2 μm obtained from 1990 August 5–12, when most of the Galactic plane was in view. Similar results are found at 1.2 μm and 3.5 μm.
