Statistical properties of the samples. Left panel: corner plot distribution of the binary sample we generated for the variables f, e, i, and q for the binary population. Right panel: same as in the left panel, but for the planet population. We deliberately omitted ${\mathcal{P}}_{\varpi }$ because for the binary and planet populations, the longitude of the pericentre ϖ is sampled from a uniform distribution between 0 < ϖ < 2 π. The vertical dashed lines represent intervals containing 16% and 84% of the sample (2σ).
