Left: cross-correlation functions, calculated for the wavelength solutions of all reference stars, with respect to the target. The maximising wavelength at each instance, presented in the figure, is then added to each wavelength solution for the correction of the spectra. Right: a zoom into the telluric O2 absorption region of the spectra, before and after the wavelength correction procedure.
