Inferred heavy-element mass vs. planetary mass. Top panels: comparison of the results obtained with CMS19+HG23 and SCvH95, for both core+envelope and fully mixed structures. The circles represent the midpoint between the upper and lower bounds of the errorbars. Middle panels: absolute difference in heavy-element mass due to the H–He EOS update. Bottom panels: absolute difference in bulk metallicity. Empty circles correspond to planets for which CMS19+HG23 leads to a higher metallicity than SCvH95. The dotted black line shows the 1/M_p curve.
