Mean monopole redshift-space (solid lines) and real-space (dashed lines) correlations, and , over ten comoving distance bins within 5 < r < 100   h^-1 Mpc, equally spaced in log    (r). We integrated over halos within the redshift interval 0 < z < 1, for the XXL, DES, and SPT surveys. For DES we considered the mass thresholds M > 5 × 10¹³   h^-1   M_⊙ and M > 5 × 10¹⁴   h^-1   M_⊙ (smaller error bars), and for SPT the mass threshold M > 5 × 10¹⁴   h^-1   M_⊙ (larger error bars shifted to the right). The error bars show the diagonal part of the redshift-space covariance .
