Left: the ejection velocity (not corrected for v_e) as a function of the radial position in the crater, with a terminus at the strength-limited crater radius (dotted lines at each strength Y). Each solid curve corresponds to one value of Y. We used an 85 m target radius, an 3000 kg m^-3 target density, and a 0.7 m impactor moving at 3 km s^-1, close to the nominal values from Paper I. Note that for small Y crater growth stops before the corresponding dotted strength limit as gravity becomes relatively important at low strengths. Right: the differential distribution of ejected mass as a function of ejection velocity (corrected for v_e) for various target material strengths Y. Only the lower target strengths correspond to the low debris velocities observed.
