Posteriors and correlations for ﹩{R}_{P}/{R}_{\star },b,e﹩ and ﹩{\rho }_{\star }﹩ for all systems. Gray regions surround 68%, 95%, and 99.7% of the data points (1, 2, and 3σ for Gaussian distributions) from darkest to lightest. Values of b tend to be symmetric around zero, so the absolute value is shown. The red dashed line indicates the statistical mode, and the dot-dashed blue line the median. Planet names are shown in the upper right corner. Axis ranges are selected to exclude the most extreme 0.1% of points to make the remaining points more clear, so some contours are cut on the edges. Note that e is not fit in the MCMC, but calculated from the ﹩\sqrt{e}\sin (\omega )﹩ and ﹩\sqrt{e}\cos (\omega )﹩ distributions.
