Bullet points represent the observed transmission spectrum previously published on Wyttenbach et al. (2015), binned 21x (the full resolution data are used for the fit). The sodium excess absorption is clearly visible within the yellow bands where optimization is performed. In the grey bands no clear signal is found, and these are used to normalize the spectrum.
