The oxygen abundance calibrations and N/O abundance ratios of ~40,000 SDSS star-forming galaxies [PDF]

, 2006
Using a large sample of 38,478 star-forming galaxies selected from the Second Data Release of the Sloan Digital Sky Survey database (SDSS-DR2), we derive analytical calibrations for oxygen abundances from several metallicity-sensitive emission-line ...
