Left panels: measured values of fσ₈ from the VIPERS survey in the two redshift bins, using the TNS model in its optimal set-up that we derived in section 8 (double damping factor: free Lorentzian + fixed Gaussian), as a function of the minimum fitting scale s_min. The maximum fitting scale s_max is always fixed at 50 h^-1 Mpc. The shaded area gives the statistical error at each s_min for the TNS model, as derived from the mocks. Right panels: the same measurements performed on the average of the mocks, i.e. plotting the results of Fig. 15 but showing explicitly the recovered values of fσ₈, to ease comparison with the data results on the left.
