    • This estimate neglects the energy barrier needed for the outflow, which is expected to be much lower than the binding energy. If the barrier (Formula presented) is known, then (Formula presented) should be multiplied by (Formula presented)

    • Because the most recent evidence indicates that energy transfer to the electronic subsystem occurs over time scales longer than those active in cascades, the electronic heat conductivity can be neglected at least as a first approximation. See Refs. 60

    • This argument relies on the observation that the melting point scales linearly with the inverse of the cohesive energy, as it does in the simple modification of the potential used here. However, we have earlier found that by modifying only the repulsive part of the interatomic potential, the melting point can be modified with no change in the cohesive energy (Ref. 30). Although it would be of some interest to examine the crater size scaling for such a change, this is not directly instructive for the main point of the present paper, namely the comparison with macroscopic scaling laws, and hence will not be done here
