Fit to the transit data. Upper panel: Phase-folded transit light curve (blue points), overplotted with the best-fitting model with fixed Ω_★, corresponding to case (iii) of Table 5 (green curve). Middle panel: Residuals to the fit shown in the upper panel. Lower panel: The difference between the best-fitting model shown in the upper panel, and the best-fitting model from case (i), where the gravity-darkening phenomenon is not included in the fit.
