Mean biasing function of VIPERS galaxies with M_B< −19.5−z − 5log (h) computed from counts in cells with radii of 4,6, and 8h^-1 Mpc . Biasing functions at different scales are indicated with different colours and line styles, as indicated in the plots. Error bars represent the 2σ rms scatter in the mocks. Different panels refer to different redshift shells. An offset δ = 0.015 was applied to avoid overlapping error bars. Curves are plotted out to δ_MAX.
