Model A distributions of orbital elements, semimajor axes, and eccentricities for an interaction resulting in a binary–binary with f_BB = 0.058 (see Table 2). Top: Semimajor axis of the two binaries. We present the tighter binary along the x-axis and the wider binary along the y-axis (explaining the empty lower-right corner bordered by the dashed line). Bottom: Eccentricity distributions of various orbits. The Kolmogorov-Smirnov test indicates that for model A, the tighter and wider distributions for eccentricity are indistinguishable. For the Figure-8 (p = 0.0064) and $I.A{.}_{68}^{i.c.}(0.5)$ (p = 0.034), the eccentricity distribution of the tighter binaries appears not to be randomly sampled from a single parent distribution.
