Intrinsic Temp. (T_int) [K]	[300, 1500]	1000 ± 30
Metallicity ([Fe/H]) [dex]	[ − 2, 3]	$0 . 1_{- 0.4}^{+ 0.8}$ $0.1^{+0.8}_{-0.4}$
Core Mass (M_core/M_⊕)	[1, 100]	Unconstrained³
Sedimentation (f_sed)	[1, 6]	$2 . 8_{- 0.8}^{+ 1.1}$ $2.8^{+1.1}_{-0.8}$
Vertical Mixing (log K_zz)	[1, 12]	$9 . 0_{- 1.5}^{+ 1.2}$ $9.0^{+1.2}_{-1.5}$
Radius (R_Jup)	Model derived	1.4 ± 0.1

Notes. All priors are uniform in the given ranges. The reported values are the median of the marginalized posterior distribution, with errors corresponding to the 16th and 84th percentiles.
