Histogram of the distribution of the void radii for the catalog of high-significance voids (blue) and for the average distribution of individual simulations (orange). The y-axis shows the actual number in each radius bin for the high-significance voids. The orange curve is arbitrarily rescaled to make it comparable. The two histograms illustrate how smaller voids in a single realization of the large-scale structure are more likely to be spurious or less significant, with only a fraction of them contributing to the final catalog.
