Comparison between the spectral and spatial Lyα properties in each component taken separately. The FWHM of the Lyα line in the core (orange) and in the halo (blue) is plotted against the Lyα emission scale length in the left panel and against the flux in the component in the right panel. The larger symbols indicate the six S/N_HALO >  10 objects. Spearman rank correlation coefficients ρ_s and corresponding p₀ values are shown in each panel. Figure A.2 (panels a3 and a5) show the relations with the peak velocity shift in the halo and the asymmetry where no correlation is found.
