Prior and posterior parameter distributions for the interior characterization assuming an Earth-like rocky composition.

Parameter	Prior	Posterior (circular model)	Posterior (eccentric model)
M_atm	𝒰(5e⁻³ − 1e⁻¹) M_p	0.05 ± 0.03 M_⊕	0.05 ± 0.03 M_⊕
M_core+mantle	$N (M_{p}, σ_{M_{p}}^{2})$ $Mathematical equation: ${\cal N}\left( {{M_p},\sigma _{{M_p}}^2} \right)$$	${5.62}_{- 0.89}^{+ 0.86} M_{\oplus}$ $Mathematical equation: $5.62_{ - 0.89}^{ + 0.86}{M_ \oplus }$$	${6.24}_{- 0.87}^{+ 0.81} M_{\oplus}$ $Mathematical equation: $5.62_{ - 0.89}^{ + 0.86}{M_ \oplus }$$
Z_env	𝒰(0.0 − 1.0)	${0.61}_{- 0.26}^{+ 0.24}$ $Mathematical equation: $0.61_{ - 0.26}^{ + 0.24}$$	${0.60}_{- 0.27}^{+ 0.24}$ $Mathematical equation: $0.60_{ - 0.27}^{ + 0.24}$$

Notes. Priors are identical for the circular and eccentric models except for the value of M_p. Posterior values correspond to the circular and eccentric solutions shown in Fig. E.2.
