Fig. 4.

Ratio of sulfur to magnesium abundance [S/Mg] as a function of the mean stellar metallicity [M/H] for stars in common with Santos-Peral et al. (2020a). The blue horizontal line indicates the median of [S/Mg] (−0.05 dex) over the whole metallicity domain and the associated median absolute deviation is reported in the upper left corner.
