Cross-correlation S/N between the ExoMol VO line list and M-dwarf spectra for each UVES-sized spectral order. The solid and dotted lines depict the observed and injected signals, respectively. Top panel: cross-correlation with the HARPS and CARMENES spectra of Wolf 359. Bottom panel: cross-correlation with the HARPS spectrumof Proxima Centauri and the CARMENES spectrum of Teegarden’s star. The grey vertical bands are regions which are not covered by the UVES spectrograph.
