Core mean quantities of all simulations, grouped by stellar mass and model. All quantities are calculated per simulation, and then averaged over the 8 simulations per group. (A) Mean total mass of the planetesimals and planets in the disc. (B) Mean maximum planet mass. (C) Mean number of Earth-like (0.67–1.5 M_E) planets. The number of Mars-like planets (0.1–0.67 M_E), and massive planets (>1.5 M_E) are stacked on top with increasing transparency.
