WASP-76b discovery data: top: the WASP data folded on the transit period. Second panel: the binned WASP data with (offset) the follow-up transit light curves (ordered from the top as in Table 1) together with the fitted MCMC model. Third: The SOPHIE and CORALIE radial velocities with the fitted model. Bottom: The bisector spans; the absence of any correlation with radial velocity is a check against transit mimics.
