“2ℓ = 2” redshift-space halo correlation . As in Fig. 1, we considered ten comoving distance bins, within 5 < r < 100   h^-1 Mpc, equally spaced in log    (r), and counted all halos above the thresholds M _∗  = 2 × 10¹³ and 10¹⁴   h^-1   M_⊙, within the redshift interval 0 < z < 0.8. We compare our analytical results with numerical simulations (crosses). The 3 − σ error bars (slightly shifted to the left and to the right for the real-space and redshift-space correlations) are obtained from the analytical covariance matrices derived in Sect. 4.
