Notes. Median and 1σ error bars of the fitting parameters of the full-phase JWST light curve between 6.5 and 7.0 µm. Limb darkening parameters u+ and u are not fitting parameters but were derived from the limb darkening parameters A and B (see Kálmán et al. 2024), so their priors are not reported in the Table.
