Notes. Columns are: name in the UNAM-KIAS catalog, physical scale (kpc, h = 0.73) subtended by the 3 arcsec SDSS fiber at the distance of each galaxy, type of spectrum and ionization source associated with the nuclear region from the modeled SDSS spectrum, log10 of the average light-weighted age (in units of yr) and its error, log10 of the average mass-weighted age (in units of yr) and its error, and the star formation timescale (in units of Gyr).
