Left panel: our best estimate of the fraction of galaxies with EW₀(Lyα) > 25 Å, as a function of the redshift, for three intervals of far-UV absolute magnitudes: faint objects (M^∗<M_FUV<M^∗ + 1) are shown in blue; bright objects (M_FUV<M^∗) are shown in red; objects with − 21.75 <M_FUV< − 20.25 are shown in green. The fiducial values, shown by the continuous thick lines, include all the galaxies with spectroscopic flag 2, 3, 4 and 9, and also all the galaxies with a spectroscopic flag 1 and a spectroscopic redshift that differs less than 10% from the photometric one. The dashed lighter lines show a finer binning in redshift. Right panel: same as left panel, but for galaxies with EW₀(Lyα) > 55 Å.
