Notes.

^(a)

Redshift of the observed Lyα peak in a quasar spectrum integrated within an aperture of radius 1.5 arcsec centered at the quasar location. The intrinsic uncertainty on this value is Δz ∼ 0.001.

^(b)

Redshift of the observed Lyα peak in the spectrum integrated within the 2σ isophote of the nebular emission.

^(c)

Observed peak Lyα luminosity density of the integrated quasar spectrum.

^(d)

Integrated Lyα luminosity within the nebular 2σ isophote.

^(e)

Area within the nebular 2σ isophote.

^(f)

Velocity shift between the quasar Lyα redshift and the Gaussian centroid of the nebular Lyα line.

^(g)

Velocity shift between the quasar Lyα redshift and the flux weighted first moment of the nebular Lyα line.

^(h)

FWHM of the Gaussian fit to the nebular Lyα line. The reported values are not corrected for instrumental broadening.

⁽ⁱ⁾

Flux weighted second moment of the nebular Lyα line.
