Catalogue of Gas Phase Metallicities

Summary

This catalogue contains estimates for 12 + Log O/H obtained from the model fits discussed by Brinchmann, J. et al 2004, in press for MNRAS, Brinchmann et al (2004) and Charlot et al (2004 - in preparation). See Tremonti, C. A., et al, 2004, in press for ApJ, "The Origin of the Mass--Metallicity Relation: Insights from 53,000 Star-Forming Galaxies in the SDSS" for details about these determinations and comparison with the literature.

About the catalogue

The catalogue contains all 261054 galaxies we have examined in the DR2. The metallicities are however only calculated for the 62133 galaxies which have S/N > 3 in Hbeta, [O III]5007, Halpha and [N II]6584 (see the paper for details). The other galaxies have metallicities set to 0.0. Please note that this is still a superset of the galaxies discussed by Tremonti et al, and we only guarantee that the valuse for 12 + Log O/H for galaxies within the selection region discussed by Tremonti et al are reliable.
