Notes.

^(a)

Redshift of the absorption components are linked.

^(b)

f is defined as the absorption depth at threshold.

^(c)

Photoelectric cross-section index.

^(d)

Linked values.

^(e)

Normalizations in units of total photons cm⁻² s⁻¹.

^(f)

WINE model normalizations are linked according to the ratio of the Lyα and Lyβ oscillator strengths.

^(g)

Derived minimum velocity of the wind (i.e., v(r) for r = 0 and r = r_cone).

^(h)

Derived opening angle of the cone.
