Notes. Abundances (and uncertainties) of magnesium per star determined from the set of individual Mg spectral lines, and from the isotope pipeline for each magnesium isotope for eight stars calculated using equations in Section 3.2.1. Reference values and uncertainties are from Jofré et al. (2015) (GBS [Mg/H]). Per isotope abundances are also given.
