TOI-283 b RV measurements taken with ESPRESSO. Panel a: RV time series and best-fitting model. The best-fitting model was computed using the median values of the posterior distribution of the fit parameters; the shaded area represents the 1σ uncertainty limits of the best-fitting model. Panel b: residuals of the fit after subtracting the single-planet Keplerian model. The uncertainties shown here include the RV jitter values (added in quadrature) for each set.
