Transit light curves of Hα (left) and He I triplet (right). The He I light curve has been constructed integrating the counts of the residual map in the planet rest frame around λ₀ using σ (blue) and FWHM (orange) wavelength band passes from Table D.1. For the Hα light curve, we considered two generic band passes. The vertical lines represent the different contacts during the transit. Note the different y-axis scales between plots.
