Mass (M_Jup) versus physical separation (AU) for all the companions in the synthetic planet populations generated as described in Sect. 5. Left panel: non-scattered population (Forgan & Rice 2013). Right panel: same population including scattering (Forgan et al. 2015). Different colors are used for single (green), double (blue), triple (orange), and quadruple (purple) systems. The size of the symbols increases from single to quadruple systems to make the plots easier to read.
