Simulated Bennu-like asteroid, with high crater density. The total saturation is nearly 25% (the surface partitioned into nearly 2000 patches) and the slope of power law B = 3. For simple craters, we have , while for fresh craters . For fresh craters, we set the degradation vector as α = (Δk = −0.2, Δγ = −0.2, Δa = −0.38). In complex crater, we set the degradation vector as α = (Δk = −0.04, Δγ = −0.4, Δa = −0.2).
