Interior structure model of Phobos. In this model, the impact that formed the Stickney crater has led to macroporosity (Asphaug & Melosh 1993), representing the main source of lateral heterogeneity. The gray part sketches the geometry that we used to compute the lateral heterogeneity, see text for details. Radial heterogeneity comes from a thick outer regolith layer and a high (macro)porosity layer created as a consequence of impacting of the material, but assumed to be laterally homogeneous, except in the region of Stickney.
