Escape fraction fesc(Lyα) and spatial distribution of Lyα, Hα, and UV continuum radiation. The two panels show the fractional contribution to the integrated flux for UV (green), Hα (red stars), and Lyα (blue squares) as a function of the far-UV surface brightness (AB mag arcsec^-2; left panel) or equivalent radius (i.e., the isophotal radius; right panel). We express here the radius in arcsec (′′; 1′′ corresponds to 0.67 kpc at z = 0.0338). The cumulative Lyα escape fraction is shown with magenta triangles. It starts out as negative and increases monotonically to finally reach 16% at large radii from the center of the galaxy.
