The published Eq. (8) in our paper (Liang et al. 2007, A&A, 473, 411) should be replaced by the formula below:(8)where x refers to 12 + log (O/H).

This does not affect our result, shown by the solid line in Fig. 7b, since it was computed with Eq. (1) here actually.


We thank Vallery Stanishev for pointing out this problem.
