Size ratio distribution of neighboring planets (R_out/R_in) in our baseline model (black, green) and the Kepler sample. Compared to Figure 6, Here we include the model for the isothermal layer of the atmosphere (Equation (25)) up to a maximum size of R_max = 0.2 ﹩{R}_{{\rm{B}}}﹩. The top plot shows the distribution for planet pairs where both planets are above R/﹩{R}_{\oplus }﹩ = 1.05(F/﹩{F}_{\oplus }﹩)^0.11. The middle plot shows R_out/R_in when there is one planet on either side of the line, and the bottom plot is for planet pairs where both planets are below the line.
