Resolution requirements for accurately reproducing the total energy deposited (left) and final blow-off momentum (right) in 1D simulations, shown for all four asteroid materials and five X-ray fluences, as a function of the number of equally spaced nodes within the deposition layer. The gray shaded region indicates agreement within ±10%. We compare the total energy and blow-off momenta to simulations from our fiducial setup above, which are overresolved.
