Phase-folded TESS LC, best model (top) and residuals (bottom) for the three transiting planets. The data presented in Sect. 2.2 are displayed in black. For clarity, the error bars are not displayed. The points with error bars in red correspond to averages of the data within evenly spaced bins in orbital phase whose size corresponds to 5 min. The best model is shown with a black line. The standard deviation of the raw and binned residuals is indicated above each residual plot.
