Left : TESS-detrended light curve phase-folded to the best-fitting period listed in Table 2 and zoomed to show the transit event. The blue and white circles correspond to modelled photometric data and binned data with the associated photon noise error. The blue line and shaded region show the median transit model and its 1σ confidence interval. Centre : same as the left panel for the LCOGT-SAAO telescope. Right : same as the left panel for the NGTS mission. Bottom : Residuals of the best-fit model.
