The marginalized best-fit ﹩{{ \mathcal M }}_{{\rm{obs}}}﹩ from the ﹩{{ \mathcal M }}_{228}﹩ model (m* = 4.5, red lines) is compared to the marginalized ﹩{{ \mathcal D }}_{{\rm{kep}}}﹩ (blue histograms and blue lines). The two columns of plots show the differential (left) and cumulative distribution functions (right). From top to bottom, the rows of plots show: the (1) radius monotonicity M_R for all Kepler systems (G. J. Gilbert & D. C. Fabrycky 2020; M. Y. He et al. 2020), (2) M_R for systems with R₁ < 2R_⊕, and (3) M_R for systems with R₁ > 2R_⊕. The green lines in rows (2) and (3) are plotted for reference: the M_R distribution for R₁ > 2R_⊕ in (2) and R₁ > 2R_⊕ in (3).
