Comparison of the orbit of a particular satellite (S5/6 according to Table 2 nomenclature) when run in isolation (cyan line) or in each one of the 20 N-body models of our ensemble, shown in the top panel (black solid lines). This figure shows the scatter between realizations that we quantified in Fig. 6, for one of the satellites. Bottom panel: histogram of distances of all close encounters between two satellites in the full ensemble of N-body models.
