SED of TOI-1438 and the model with highest probability (Castelli & Kurucz 2004) are plotted together with the synthetic photometry (magenta diamonds) and the observed photometry (blue points). The vertical error bars outlines the 1 σ uncertainties and the horizontal bars the effective width of the passbands. The residuals of the fit (normalised to the errors of the photometry) are shown in the lower panel.
