and we also plot the fit function in the same figure. ) and σc,λ=1 L (r s ) (Fig. ) can be observed for large r s values. In the former case (no N L counterpart in σ), the saturation is very slow at large r s , whereas in the latter case (with N L counterpart) it is much faster and already for r s values larger than ∼ 10, σc,λ=1 L changes very little. This shows that the ability of the N L part of σ to capture the long-range correlations makes an easier job for its L counterpart to capture the remaining physics.
