Notes. Original samples have been modified to reflect the cosmological model described in Sect. 1. Column 1: source name in reported Besselian epoch and Julian conversion (where B1950 declination has 3 significant figures, J2000 conversion is only accurate to the nearest 10¹ arcminute). 2: References (A ≡ O’Dea & Baum 1997, B ≡ Snellen et al. 2000, C ≡ Snellen et al. 1998, D ≡ de Vries et al. 1997, E ≡ Stanghellini et al. 1998, or F ≡ Fanti et al. 1990) and optical identification (Q ≡ Quasar, G ≡ Galaxy, and U ≡ Unlisted in reference). 3: Redshift (set to 1 if unknown). 4: Angular size. 5: Observed frequency of spectral peak. 6: Projected linear size. 7: Turnover flux density. 8: Thick spectral index. 9: Thin spectral index. 10: Power at 5 GHz.

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.

Initial download of the metrics may take a while.
