Notes. MCMC output parameters (see Sect. 5.2). The results are shown for the two different compositional scenarios and for the two models considered (water as the only volatile - upper part - and a H/He atmosphere - bottom part). (a)Only the mass and radius of the planet are considered as inputs. (b)In addition to the planetary mass and radius, the stellar Fe/Si mole ratios (see Table 2) are also included as input data.
