Correlation function measured for “all” lags (see text for details) as a function of the pair separation s, with a random catalog size of N_rand = 5000. The lines denote the mean ξ(s) measured in the 125 subcubes using the different estimators listed in , and the gray shaded region shows the standard deviation. In the left panel, the s-range from 8 to 40 h^-1Mpc is plotted, and the right panel shows the results for very small lags, from 4 to 8 h^-1Mpc.
