Notes. 

(a)

QSO redshift taken from the PG, HES, or SDSS catalogues.

(b)

Apparent B band magnitudes taken from the catalogues or synthesised from the SDSS spetrum.

(c)

Absolute magnitudes MB taking into account Galactic foreground extinction and an appropriate k-correction (Wisotzki 2000).

(d)

Radio fluxes at 1.4 GHz in mJy as measured by the NVSS all-sky survey or the FIRST survey when available.

(e)

Radio fluxes at 5 GHz in mJy taken from Kellermann et al. (1989) and an unpublished catalog (Gopal-Krishna et al., priv. comm.), if available. Values marked with † were estimated from the radio flux at 1.4 GHz assuming a spectral index of α =  −0.5.

(f)

Ratio R of the 5 GHz radio to optical flux density at 4400 Å. The optical flux density fν(4400   Å) in mJy was estimated from the optical B band magnitude with the relation mB =  −2.5log fν(4400   Å) − 48.36 (Schmidt & Green 1983).

(g)

Radio classification of the QSO following Kellermann et al. (1989) into radio loud (RL) and radio quiet (RQ) and radio intermediate (RI) QSOs. An unambigous classification for a few object cannot be made due to upper limits in R.

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.
