MR distribution of the selected observed planets in comparison to modeling results. The symbol color indicates the approximate planetary equilibrium temperature as given in the legend. The largest uncertainties are 45% on planetary mass and 15% on planetary radius. The solid and long-dashed lines enclose the maximum predicted spreads in planetary radius at the age of 5 Gyr, obtained by considering the entire set of atmospheric evolutionary tracks computed in the 512–680 K (light blue lines) and 1350–1700 K (orange lines) temperature intervals, where the upper boundary is given by the migrated scenario. For reference, the short-dashed lines show the upper boundary predicted for the basicsetup scenario.
