Binary mass ratio vs. binary separation (top panel) and binary mass ratio vs. disc truncation radius (bottom panel) for systems that formed a planet at least more massive than Mars. The colour bar indicates the final planet mass. The shaded contour regions represent areas with the highest number planet density, derived from a two-dimensional KDE performed on planets with masses greater than 10 M_⊕. The lack of planets for R_trunc>400 au stems from the choice of the upper limit on a_bin = 1000 au (see Table 1).
