VizieR Online Data Catalog: Barred & unbarred galaxies N, O abundance ratio (Florido+, 2015)

The tables contain nebular emission line fluxes for the central region of 251 barred and 324 unbarred galaxies. The sample contains all spiral face-on galaxies (axial ratio b/a>=0.9) in the SDSS DR-2, with stellar masses larger than 10¹⁰ the solar mass, redshift 0.02<z<0.07 and 0.07, bulge-to-total luminosity ratio above 0.043, and signal-to-noise ratio in their corresponding SDSS spectra greater or equal than 10 (in g-band). See Sect. 2 of the paper and Coelho & Gadotti (2011ApJ...743L..13C) for further details about the galaxy sample.
