Notes.Columns: 1) running number; 2) D4000n index; 3) E(B − V) derived from the Hα/Hβ ratio after correction for underlying absorption; 4) fiber u − g colour, corrected for extinction assuming a foreground screen; 5) fiber g − r colour, corrected for extinction; 6) the [O iii]λ5007/Hβ ratio; 7) oxygen abundance derived from the ON and ONS methods according to Pilyugin et al. (2010); 8) the exponential scale length in the Hα continuum; 9) the Hα scale length; 10) equivalent width of Hα in emission derived from our measurements of the SDSS spectra (NEW) and as given in the SDSS data bank (SDSS); 11) the Hα equivalent width within a circular aperture of 10 arcseconds radius.
