Notes.
Applying values from Table 5 of AGSS09, based on GCE models of Chiappini et al. (2003);
Cescutti et al. (2007), based on Cepheid observations of Andrievsky et al. (2004, and references therein);
a slightly steeper – though compatible – gradient, by − 0.044 ± 0.010 dex kpc-1, is given by Carigi et al. (2005).
