Summary: The supplementary information contains three sections: 1) model results; 2) benchmarking and comparisons with
smoothed-particle hydrodynamics (SPH) approach; 3) discussion of ejecta curtain velocity and behaviour.
1. Model Results
Run parameters and outputs are summarized in Table S1. Impactor velocities are those at the surface of Mars.
