Redshift-space galaxy clustering ratio η_g,R(nR) (LHS of Eq. (21)) extracted from 160 independent LasDamas simulations of the distribution of luminous red galaxies (LRG, see Sect. 4). The observable η_g,R(nR) is shown as a function of the smoothing radius R for four different values of n as indicated in the key. Simulated observations are compared to the predicted amplitudes of the real-space mass clustering ratio η_R(nR) (RHS of Eq. (21)) for the same values of n. Dot-dashed lines show predictions obtained using a linear power spectrum, while solid lines are derived using the non-linear (halofit) model of Smith et al. (2003). Both the galaxy and mass clustering ratios are derived by adopting the same cosmological parameters of the LasDamas simulations. Error bars represent the uncertainties expected from a redshift survey covering a volume 160 times larger than that explored by the LRG sample used in this study.
