One- and two-dimensional posterior likelihood distribution of the derived parameters fσ₈, bσ₈ and σ₁₂ for the 0.5 <z< 0.7 redshift bin. This corresponds to the result of the analysis of VIPERS data using the dispersion model, the Scoccimarro model, the Taruya model, and s_min = 5h^-1 Mpc. The dark- and light-shaded areas correspond to the 68% and 95% joint two-parameter confidence levels, respectively. The lower redshift sample shows comparable contours and shapes.
