Notes. Comparison of Mg isotope ratios with uncertainties derived in this study with literature values Barbuy (1985) (B85), Barbuy (1987)(B87), McWilliam & Lambert (1988)(ML88), and Gay & Lambert (2000)(GL00)) for the three reference stars HD 23249, HD 128621, and HD 10700. Additional rows include literature values for stars with similar stellar parameters from Gay & Lambert (2000) (GL00) and McKenzie et al. (2024b) (MM24).
