Notes.

(a)

In units of km s−1.

(b)

Rest frame EWs reported with normalised spectra at 1700 Å are in units of Å.

(c)

UV diagnostic ratios from MS14 for Pop. A sources.

(d)

UV diagnostic ratio from MS14 for Pop. B sources.

(e)

Log of MBH are computed using the scale relations by M22 in units of M⊙.

(f)

Log of line luminosity in units of ergs s−1; uncertainties are 10% of the value.

(g)

Log of bolometric luminosity in unit of ergs s−1 computed using the continuum window at 1700 Å.

(h)

REdd is the Eddington ratio.

(i)

Log of virial luminosity in units of ergs s−1; uncertainties are 10% of the value.

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.
