Notes. The discrepancies Δ[M/H] and Δ[X/M] are calculated from the solar zero-point at the time of the birth of the Sun. The last two columns contain the estimated abundance precision based on solar neighborhood and the overall assessment category of precision adopted from Meszaros et al. (2025), under rev.). Note that ⊗ drives caution to V. The f_X are dimensionless scaling factors, while the other columns are in units of dex.
