Difference between the Ernst et al. (this study) Phobos global shape model and those of Gaskell 2011 (top) and Willner et al. 2014 (bottom). All three models are in generally good agreement with one another. The new model is nearly the same as the previous models in some areas (white in the color scale), larger in some areas (green in the color scale), and smaller in some areas (brown in the color scale). The new model on average is slightly smaller (30–40 m, corresponding to ~ 0.3–0.4% of the mean body radius; ~ 1% smaller in volume) than the two previous models
