Systematic Effects in Color Photometry Data

Abstract

Previous work with laboratory and field observations and computer simulations suggests that classes of spacecraft can be distinguished on the basis of their color or spectral properties. Empirical results also indicate that accounting for systematic effects reduces much of the observed scatter and thus increases separability of the classes. We seek to gain an understanding of the basic properties of satellite features that determine the spectral characteristics of individual satellites: surface materials and scattering properties, combination of materials, shape, orientation, illumination-viewing geometries, etc. Initial efforts have focused on systematic effects of solar phase angle on object brightness and color data.
