Notes. Column description: (1) source name; (2) redshift; (3) Galactic absorption; (4) logarithm of the luminosity of the Hα narrow line, in erg s-1; (5) logarithm of the Hα flux in erg cm-2 s-1; (6 through 11) de-reddened flux ratios of the key diagnostic lines with respect to Hα. The values in parentheses report the errors (in percentage) of each line; (12) logarithm of the flux of the Hα broad component, when visible.
for 3C 346 no measurement of Hα is possible and we give instead the [O III] luminosity, referring the flux ratios to this line. Data for 3C 270 are taken from Ho et al. (1997) and corrected for Galactic reddening.
