Time folded transit light curves of WASP-103b obtained with Spitzer 1, Spitzer 2, CHEOPS, and HST. The CHEOPS transit light curve is a combination of 12 individual transits, while the HST light curve is a combination of two transits. The best fit ellipsoidal transit model is shown in blue. We also plotted the residuals of the best fit ellipsoidal model (blue) and the best fit spherical model (red) binned to 5 min. On the latter, we overplotted the signature of the deformation(green) which is the difference between the best fit spherical model and the best fit ellipsoidal models. For clarity, we replotted a zoom of the signature of the deformation in the bottom panel for each filter. We also show the mean uncertainties of the original data points and of the binned residuals.
