WASP-43 radial velocities. Red dots represent HARPS-N data while blue open circles are CORALIE data. Top panels: phase-folded RVs with the best-fit RV curve superimposed, and below the corresponding residuals. Middle panel: RV residuals plotted as a function of the Barycentric Julian Date (BJD) show no evidence of a long term RV trend. Bottom panel: zoom in the RV time-series covering the transit. To highlight the RM effect, the orbital RV trend was subtracted.
