Notes.

^(a)

Line peak wavelength from the Gaussian modelling of Lyα- and CIV-CEN spectrum.

^(b)

Redshift of the CEN corresponding to λ_CEN. We used as Lyα and CIV λ rest-frame 1215.67 Å and 1549.48 Å, respectively.

^(c)

Maximum projected physical size derived from the 3D-mask.

^(d)

Spectral width within which the CEN was detected (from 3D-mask).

^(e)

Distance from the quasar position to the SB peak of the CEN.

^(f)

Distance from the quasar position to the flux weighted centroid of the CEN.

^(g)

Asymmetry parameter, i.e. the ratio between the semi-minor and semi-major axis of the SB map.

^(h)

Position angle east of north of the major axis of the SB map.

⁽ⁱ⁾

Total flux derived from the SB maps (Figs. 1 and 4).

^(j)

Total CEN luminosity.

^(k)

Averaged velocity dispersion measured from the S/N ≥ 3 velocity dispersion maps (see Sect. 4.3) of the Lyα and CIV.

^(l)

Velocity dispersions derived from the Gaussian fit of the total Lyα- and CIV-CEN spectrum.

^( ⋆ )Errors according to the spatial resolution of MUSE data.

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.
