Notes. FWHM is the average full-width at half maximum of the lines used (in Ångström) and BIS is the corresponding bisector spans. S/N is the signal-to-noise ratio of the individual spectra. The FWHM of the FIES CCFs are wider than those extracted from the HARPS spectra because of the different resolutions of the two spectrographs.
