Challenges of Dawn FC data Photometry of Ceres
Abstract
We discuss non-instrumental systematic deviations from global photometric properties in specific contexts. Besides resolution based influences the high dynamic range of reflectances, local constitutional properties of the surface and superposed semitransparent materials affect the scattering of light. Among others, the complicated case of crater Occator on Ceres requires most careful assessment of the true local photometric model, in contrast to an immediate application of a global model. Problems, methods and limitations of analysis are addressed.
