The spatial correlation function of rich clusters of galaxies

摘要: A series of objective statistical estimators is applied to directly study the three-dimensional distribution rich clusters, using a recently completed redshift sample 104 Abell clusters out distance class four and galactic latitude 30 deg or more. The relevant positional selection effects are discussed, two-point angular correlation function nearest-neighbor in determined, as well larger D = 5+6 several subsamples different richness classes zones. for various separations on sky examined test reality observed correlations. spatial consistency among three functions tested. model that describes all correlations presented.
