Mean biasing function of VIPERS galaxies with M_B< −19.5−z − 5log (h) measured in different redshift bins, characterised by different colours and line-styles, as indicated in the plot. Error bars represents the 1σ scatter in the mocks. The three panels refer to different cell sizes with radii R = 4,6,8h^-1 Mpc  from top to bottom. A horizontal offset δ = 0.015 was applied to avoid overlapping error bars. All curves are plotted out to δ_MAX.
