Reanalyzed radii vs. masses of all the planets in our sample. The colors of data points are determined based on equilibrium temperature, according to the colorbar. Several composition curves are overlaid. A curve corresponding to an Earth-like composition from Zeng et al. (2019) is shown as solid green line. Curves corresponding to water mass fractions of 3% (dash-dotted) and 10% (dotted) are shown at 400, 700, and 1000 K, and are linearly interpolated based on the same pretabulated models discussed in Section 6.4.
