Notes. Column description: (1) 3CR name; (2) redshift from Spinrad et al. (1985); (3) and (4) logarithm of Hα and [O III]λ5007 luminosities [erg s-1]; (5) radio luminosity at 178 MHz [erg s-1 Hz-1] from Spinrad et al. (1985); (6) radio core power at 5 GHz [erg s-1 Hz-1] from Baldi & Capetti (2009); (7) host H magnitude from 2MASS (Skrutskie et al. 2006) (or from HST (Donzelli et al. 2007) for the objects marked with a ∗); (8): morphological FR type; (9) spectroscopic classification into High Excitation Galaxy (HEG); Low Excitation Galaxy (LEG); Broad Line Object (BLO); (–) unclassified. Column (10) classification method: E.I. – excitation index; D.D. – diagnostic diagrams.
