Top: TESS phase-folded transits after subtracting the GP-modelled activity, along with the transit model shown with a black line and the residuals below it. Bottom: HARPS-N phased curve of RV data after subtracting the GP-modelled activity, with the planetary RV model (black line) and the residuals plotted below. The RV error bars are plotted without the jitter, the value of which is reported in Table A.2.
