Eccentricity distributions for the Kepler-10b planets that do not reach the threshold ﹩{a}_{1}(1-{e}_{1}^{2})\lt 0.02\,\mathrm{au}﹩ to become USP planets in our fiducial integrations (e, i from Rayleigh with σ = 0.1 and t_max = 30 Myr). The red line indicates the time-averaged distribution of the ensemble, while the black line shows the initial distribution. For reference, the thin dashed lines show the Rayleigh distributions with σ = 0.1 (black) and σ = 0.2 (red). The distributions are normalized by the tallest bin.
