Decomposition of the observed Lyα surface brightness distributions into a compact (continuum-like) and an extended exponential component (halo), as described in the text. Only the objects with detected haloes (p₀< 0.05) are shown. The datapoints are the same as in Fig. 4, but now plotted against linear radii. The green curves show the profiles of the continuum-like components (dashed for the objects without HST counterparts and thus assumed to be point sources), the thin blue lines represent the extended haloes; both convolved with the MUSE PSF. The thick blue lines show the sum of the two components.
