The values of the excitation potential, $\chi$, and oscillator strength, $\log gf$, of the three lines of the Mg Ib triplet at 5167-83 Å in Table 2 are wrong. The correct values are:

Mg I $\lambda$5167.321 Å: $\chi=2.709$ eV and $\log gf=-1.03$
Mg I $\lambda$5172.684 Å: $\chi=2.712$ eV and $\log gf=-0.40$
Mg I $\lambda$5183.604 Å: $\chi=2.717$ eV and $\log gf=-0.18$.

All the synthetic spectra, as those displayed in Fig. 9, presented in the paper were computed using the correct values for the excitation potential and oscillator strengths of these Mg I lines. Therefore, although we made a mistake in writing the values of $\chi$and $\log gf$ of these lines in Table 2, the Mg abundances presented in the paper are also correct.
