Relative systematic error on fσ8 at 0.5 <z < 0.7 as a function of smin, for different values of r0 (r0 = 1 h-1 Mpc and r0 = 1.5 h-1 Mpc) and when including or not redshift error. The error bars represent the relative statistical error associated to analysing the mean mock predictions. The shaded area shows the 1σ confidence region associated with the relative statistical error expected in VIPERS. The squares and triangles are artificially shifted along smin axis to improve the clarity of the figure.
