Notes. Column description: (1) source name (we report the sources for which we obtained new measurements in boldface) and spectroscopic classification. For 3C 079 and 3C 227 we considered two regions, across (A) and along (J) the jet; (2) region size (arcseconds); (3) distance of the region considered from the nucleus in arcseconds and (4) kpc, (5) angular offset between the radio axis and the fitted region (6), (7), (8), and (9) diagnostic line ratios, (10) spectroscopic classification of the extended region.
