Comparison between our results obtained from combining six transits observed with HARPS-N (black) and that published by Casasayas-Barris et al. (2019) employing HARPS-N (three transits; red) and CARMENES (one transit; blue). The top, middle, and bottom panels show the comparison for the Hα, Hβ, and Ηγ lines, respectively. The central wavelengths of the Balmer lines (in vacuum) used to convert the wavelengths into velocities are 6564.60 Å for Hα, 4862.71 Å for Hβ, and 4341.69 Å for Ηγ. Lines correspond to the original data, while to guide the eye dots are the data binned to about 7.5 km s⁻¹. The vertical and horizontal dotted lines respectively at zero and one are for reference. The HARPS-N transmission spectra of Casasayas-Barris et al. (2019) are about 20% noisier than those presented here.
