Velocity offsets of Lyα determined with respect to the C III detections as a function of the Lyα rest-frame equivalent width estimated for a fixed UV slope of β = −1.97. The gray dot-dashed and dotted lines show the empirical relationship between Δv_Lyα and equivalent width for z ≈ 3 objects presented by Nakajima et al. (2018) and Adelberger et al. (2003), respectively. The individual points are color coded according to redshift.
