Spectra around the observed sulphur lines in three stars (ET0121, ET0027, ET0232) as (black) crosses. Solid (red) lines show the best fits to each line, as listed in Table A.2. These three stars cover the metallicity range of the sample ([ Fe / H ] = −2.35, −1.50, −1.00), and have typical S/N for the target stars, within 1σ from the mean (S/N = 68,69,54).
