Notes. Using oxygen and iron abundances of MW disc main sequence turn-off stars from the third data release of the GALAH survey (Buder et al. 2021) grouped in 14 age bins. Stellar ages come from the catalogue by Sharma et al. (2018). Sample selection criteria follow Hayden et al. (2022). Abundances are converted to Grevesse & Sauval (1998) solar scale.
