Cumulative number of craters per unit surface, on (15094) Polymele, (11351) Leucus, (21900) Orus and (3548) Eurybates. Results gathered from a run under case A (α_S = 0.4). The parameter for rocky material are (κ₁, κ₂, ν, μ)=(0.93,1,0.4,0.55), using Y=10 kPa for soft rock (dashed lines) and Y=1 MPa for hard rock (solid lines). The parameter for porous material are (κ₁, κ₂, ν, μ)=(0.725,1,0.4,0.4) (dotted lines), grey lines indicate crater saturation levels, with a dashed line indicating 10% and a dotted line 100% of geometric saturation.
