Phase-folded RVs of TOI-771 b and c and global RV model from the joint analysis. In the phase-folded plots, the coloured points shows the ESPRESSO data (with over-phased points in grey), and the solid black line shows the best-fitting model, with the ±1σ region displayed as a shaded area. Residuals are shown in the bottom panel. The jitter term has been added in quadrature to each error bar.
