Dependence on the minimum fitted scale, s_min, of the estimate of fσ₈ from the VIPERS PDR-2 data, using a volume-limited sample of luminous blue galaxies (blue circles). We also show for comparison, for the reference s_min =5  h⁻¹ Mpc, estimates based on the auto-correlation of VIPERS luminous red galaxies (red square) and from the blue+cross joint fit (green diamond). All estimates use the Scoccimarro model.
