Modelling of photometric and spectroscopic time series obtained from the joint fit assuming a circular model. (Left) Photometric modelling of the TOI-4602 b planetary signal. The top panel displays the normalized, phase-folded TESS transits overlaid with the best-fit model (black line), while the bottom panel shows the residuals between the observed data and the model. (Right) Phase-folded RV fit of TOI-4602 b planetary signal. The reported error bars include the jitter term, added in quadrature. The bottom panel displays the residuals of the fit.
