TESS sector 38 light curve of v² Lup. Top panel: raw light curve obtained by binning the 20-s cadence data into 2-min intervals (blue points with error bars), together with our best-fit model (orange curve), which includes the transits of planets b and c, and the GP model used to account for the correlated noise. Middle panel: light curve obtained after subtracting the GP component of our model, together with our best-fit transit model (orange curve). Bottom panel: residuals resulting from the difference between the detrended light curve and the transit model. For all panels, the error bars of the data points include the fitted additional jitter term added in quadrature. The open black circles show the light curve binned into one-hour intervals.
