Excess of surface mass density profile around random centres for the three redshift bins into which the AMICO clusters have been divided: low (0.1 ≤ z < 0.3), intermediate (0.3 ≤ z < 0.45), and high (0.45 ≤ z ≤ 0.6) redshift. We created 10 000 realisations of the sample using random centres. The blue crosses, red diamonds, and green triangles show the average measurements in the three redshift intervals, extending the profiles up to 35 Mpc h⁻¹ as in the 1h + 2h case. The black line displays the average over all redshifts. The error bars show square root of the diagonal terms of the corresponding covariances C_Randoms(r, r′). The vertical pink area on the left gives the data points below 0.2 Mpc h⁻¹, which we do not consider in our analysis.
