Top panel: absolute magnitude in the far-UV band as a function of the redshift, for all VUDS galaxies at 2 <z< 6 (gray diamonds), for the galaxies with EW₀> 25 Å (blue circles) and for the galaxies with EW₀> 55 Å (red circles). The green continuous curve indicates the evolving M^∗ as a function of the redshift as derived from the compilation by Hathi et al. (2010); the dashed green curve indicates M^∗ + 1. The vertical dashed line shows z = 3.5, the redshift up to which the faint sample is complete. Bottom panel: redshift distribution of the all the VUDS galaxies at 2 <z< 6 (black line) and of the VUDS galaxies with EW₀> 25 Å (blue histogram) and EW₀> 55 Å (red histogram).
