Comparison of different redshift ranges. Top panel: projected two-point correlation function in three redshift ranges 0.1 < z < 0.5, 0.1 < z < 0.3 and 0.3 < z < 0.5. Data points are the two-point correlation function estimates from the CODEX clusters. The solid curves in corresponding colors show the predicted dark matter two-point correlation function scaled by computed within each cluster subsample. Bottom panel: relative difference between the two-point correlation function estimate and the corresponding prediction. The data points have been shifted horizontally for clarity.
