Notes. Column 1: source name; 2: source class; 3−5: major axis, minor axis in arcseconds and position angle of the major axis in degrees; 6: source angular size extracted from FIRST (F) or NVSS (N) catalogues; 7: linear size computed using H0 = 100 km s-1 Mpc-1, q0 = 1) 8: EVN structure; 9: ROSAT X-ray flux (Perlman et al. 1998; Landt et al. 2001); 10: X-ray luminosity computed using www.astro.soton.ac.uk/~td/flux_convert.html with cosmological parameters H0 = 70 km s-1 Mpc-1,Ωm = 0.27,Ωvac = 0.73 11: nH column density (computed for cone radius of 0.5 deg from input position using heasarc.gsfc.nasa.gov/cgi-bin/Tools/; numbers are (LAB Average + DL Average nH) / 2); 12−13: polarisation percentage at 8.35 GHz and 10.45 GHz (Mantovani et al. 2011). The median value of m for CSS at 8.35 GHz is <1% (Mantovani et al. 2009); 14: rotation measure (Mantovani et al. 2009).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
