Extended Data Fig. 2: Astrophysical parameters obtained from fits to the broadband light curve.

Results are reported for fits adopting first-order and second-order sinusoidal models for the planetary phase variations. Values listed for free parameters are posterior medians and uncertainties give the 1σ credible ranges. Note that inclination i values have been derived from b and a/R_★. The redistribution factors A_F have been derived from the distribution of phase curve models sampled during fitting. Although the white noise was treated as a free parameter for each dataset as described in Methods, the quoted χ² and BIC values were calculated assuming photon noise to allow direct comparison of the two models.
