Comparison of statistics across models: ξ(r) (top left panel), v_∥(r) (top right), σ_∥(r) (bottom left), and σ_los(r) (bottom right). The left and right columns in each panel are for pair separations r = 1 and 5h^-1 Mpc, respectively. The upper rows show absolute values of the statistics, while the lower rows show the fractional deviation from GR (Δ_X = X_MG/X_GR−1 for quantity X). The red points are taken from the f(R) model results presented in Hellwing et al. (2014). (These authors binned in M_200c, the mass measured at the radius where Δ = 200 with respect to critical density; throughout this paper, we have consistently used M_200b, which is measured with respect to the background matter density. The difference in the curves when M_200c is used is negligible, however.)
