A AFM images of the thin film sample (left image in the bottom row) and the pressed pellet (right image in the bottom row). The top panel shows the surface inclination angle distribution for both experimentally used sample types, thin film (blue) and pellet (orange). The means of the distributions are marked by the respective vertical dashed lines and arrows. The inset defines the local inclination angle θ as the angle between the local and the global surface normal. B Example of the regolith structure with a porosity of about 0.840, which was used to simulate the sputter yield for the regolith case.
