Ion	λ _lab	λ _em	λ _abs	λ _∞	EW (Å)	FWHM (Å)	v (km s^-1)	v_∞ (km s^-1)

N V	1238.82	1238.60	1237.39	1237.10	0.33	0.35	290	360
N V	1242.80	1242.58	1241.39^a	1241.02	0.29	0.30	290	380
C IV	1548.20	1547.94	1546.40^a	1545.92	0.39	0.48	300	390

Notes.λ_em: Wavelength of the maximum of the emission. λ_abs: Wavelength of the minimum of the absorption. λ_∞: Wavelength of the absorption edge. v = c (λ_em − λ_abs)/λ_lab. v_∞ = c (λ_em − λ_∞)/λ_lab.

^(a)

The absorptions at 1241.39 and 1546.40 Å are affected by a weak emission.
