Comparison between scale-length for the UV first component r _1,UV and the Lyα first and second component r _1,Lyα , r _2,Lyα . r _1,UV are those obtained from a one-component fit, while r _1,Lyα are from a two-component fit. In each panel, we list Spearman’s rank correlation coefficient ρ and p-value p. The diagonal line in the left panel shows the 1:1 relation.
