2002A&A...384..140A

Based on spectra obtained at the Anglo-Australian Observatory, we present a discussion of the metallicity of the galactic disc derived using Cepheids at galactocentric distances of 4-6kpc. Our new results together with previous gradient determination (Paper I, Andrievsky et al., 2002A&A...381...32A) show that the overall abundance distribution within the galactocentric distances 4-11kpc cannot be represented by a single gradient value. The distribution is more likely bimodal: it is flatter in the solar neighbourhood with a small gradient, and steepens towards the galactic center. The steepening begins at a distance of about 6.6kpc.
