Left panel: Correlation functions for clusters with M_halo > 5 × 10¹³h^-1M_⊙ in six different redshift slices. The dashed lines show the corresponding power-law best-fits. The parameter values for the fits can be found in Table 1. Right panel: Correlation functions in the redshift slice 0.4 < z_c < 0.7 for four different mass cuts (with units h^-1M_⊙). The dashed lines show the corresponding power-law best-fits. The parameter values for the fits can be found in Table 1. Error bars are the square root of the diagonal values of the covariance matrix calculated from the jackknife resampling method.
