Accuracy of our models and our numerical simulations at redshifts z = 0.35, 1, and 3 for the real-space two-point correlation function. As in Figs. B.1 and B.2, the red solid line “direct” is the relative difference (46) between the simulations and our model as described in Valageas & Nishimichi (2011), while the green dashed line “tang.” corresponds to the geometrical modification shown in Fig. 14. The black dashed line shows the relative statistical error (which grows at large x) and shot-noise error (which grows at small x) of the simulations.
