Binary orbital parameters for the simulated binaries compared to the 35 observed TNBs (black crosse s) with full orbit solutions (Grundy et al. 2019, Table 19). Again, marker shape and colour represent the cloud masses (Fig. 2), but here we use larger bold points to highlight systems with m₂ ∕m₁ > 0.1 and (m₂ + m₁)∕M_c > 0.1, i.e. the observable binary systems. The smaller faint points represent all other systems in the dataset, i.e. the satellite systems andatomistic binaries.
