FCO fit to the HARPS-N RVs. Upper panel: Phase-folded RV model (green line) of TOI-1416 b, which corresponds to the best fit from the FCO method, obtained by vertically offsetting nightly chunks of RV data against the model. RV points from the same nights have identical colors. Lower panel: Small section of the RV model plotted against time, with RVs from three different nights.
