RV measurements from CHIRON (black circles), HARPS (green squares), and TRES (blue triangles) as a function of orbital phase. The error bars include the fitted jitter term. The units of the horizontal axis are chosen so the time of transit is at 0.25. The solid red line is the best-fitting model, based on the transit photometry as well as the RV data. The fitted value of the systemic velocity has been subtracted from both the RVs and the model. The bottom panel presents the residuals between the data and the best-fit model.
