Sample of ten light curves out of 117 distributed over the 2.85–5.17 µm wavelength range. Each light curve covers a 0.02 µm wavelength bin. Left: transit light curves (coloured points) and best-fit models (black lines). Right: residuals. The central wavelength of each bin is indicated on the right. Systematic trends have not been removed in the left panel and are extremely small. These light curves were obtained with the TEATRO reduction. The light curves are offset for clarity.
