Photometry and spectroscopy of HD 189733. Top: z‐band photometry during a transit, along with the best‐fitting model (solid line). Middle: Radial velocities as a function of orbital phase (expressed in days), along with the model (solid line). Bottom: Close‐up near the midtransit time. In all cases, the residuals (observed−calculated) are plotted beneath the data.
