We summarize the impact parameters of the four simulations that have a similar impact speed of 5 km/s and variable impact angle (θimp) and impactor diameter (Rimp). We report the corresponding impact energy relative to the catastrophic disruption threshold (Q/Q*, see ref. 62), the fraction of reaccumulated aggregates that are oblate spheroids (arbitrarily defined as having a minor-to-major axis ratio > 0.75, Foblate), the impact-induced change in temperature at the center (ΔTcenter) and the degree of compaction at the center (Ccenter). An object is fully compacted (no microporosity) when C = 1 and has its original microporosity when C = 0. The center is defined as the subset of material originally within a radius of 5 km from the center of mass of the parent body.
