Lyα emission spectral properties (same as Fig. A.2) plotted against, from left to right: Lyα EW0, the absolute UV magnitude, the UV continuum slope and the redshift of the host galaxy. The larger symbols indicate the six S/NHALO > 10 objects. Spearman rank correlation coefficients ρs and corresponding p0 values are indicated. Open circles represent the objects for which the core/halo Lyα lines are not statistically different (see Sect. 5.4).
