Simulated and observed crater SFD for Ceres (top) and Vesta (bottom) in the run that produces the best fit. The solid line represents an angle of 45° for all impacts, while the top part of the shaded area indicates an impact angle of 90° and the bottom part and angle of 15°. The crater counts were taken from Liu et al. (2018) and Gou et al. (2018). In the case of Ceres (top), a second line is observed, which is made of the crater catalog of Gou et al. (2018) with the addition of two large depressions suggested by Marchi et al. (2016).
