Mean biasing function of VIPERS galaxies from counts in cells of radius 6 h^-1 Mpc  as a function of the B-band magnitude cut in three redshift ranges indicated in each panel. Curves with different colours and line styles correspond to the different magnitude cuts indicated in upper panel. Error bars with matching colours represent the associated 1σ uncertainty intervals estimated from the mocks. A horizontal offset δ = 0.015 was applied to avoid overlapping error bars. All biasing functions are plotted out to δ_MAX.
