Notes. In the first lines of each section (marked with a dagger), the projectile and target porosity are set to 40%, and in all the other cases, the projectile and target porosity are 10 and 60%, respectively. The table columns report the (i) projectile diameter L, (ii) impact velocity vi, (iii) crater diameter at the pre-impact surface Dsurf, (iv) and (v) crater diameter Dc and depth dc, respectively, and the (vi) depth-to-diameter ratio dc/Dc.
