Cumulative distribution of the eccentricities for the inner (panel a) and outer (panel b) orbit, colour-coded as in the previous figures (outcome). The dotted grey lines follow specific power-law distribution e^η where η = −1 correspond to mostly circular orbits, η = 0 to a uniform distribution and η = 1 to a thermal distribution (e.g. mostly eccentric orbits). As in Figure 3, the coloured distributions consider the final state of a binary where it can still be considered a binary (and not destroyed). Best-fit parameters can be found in Table C.1.
