Photometric observations of TOI-2257 with the best-fit transit parameters over-plotted. Thick black points show 10-min bins, with all data points shown in gray. Residuals from the model fit are shown with an arbitrary offset below the transit. It should be noted that, for the sake of clarity, only 10-min-binned residuals are shown. The color of the line reflects the filter used for the observations (red for TESS, orange for I+z, green for i’, blue for z’, and purple for r’).
