Radial velocities of WASP-47. Upper panel: RV plot. There is a different marker and color for each data set. The TRADES best-fit RV model is plotted with open black shapes. The maximum-likelihood orbital solution is shown by a light gray line. The CORALIE data set was divided into three data sets, as described in Almenara et al. (2016). Lower panel: RV residuals with respect to the TRADES RV best-fit model. The corresponding jitter determined from the best-fit model has been added in quadrature to the measured uncertainty of each data point.
