Regularity in the distribution of superclusters
Martin Kerscher
Abstract
Using a measure of clustering derived from the nearest neighbour distribution and the void probability function we are able to distinguish between regular and clustered structures. With an example we show that regularity is a property of a point set, which may be invisible in the two point correlation function. Applying this measure to a supercluster catalogue we conclude that there is some evidence for regular structures on large scales.
