Box-and-whisker plots for the correlation coefficients r_n and the transformed values x_n, as defined in Eq. (7), where each data point shows the upper and lower quartile (edges of the box), median (line inside the box), and mean upper and lower boundaries (whiskers) for the 125 realizations measured from the simulation subcubes. These use the same lags, random catalog size, and estimator as before (see text and previous figure captions for details).
