More on Abell Clusters
Complete Northern Sample:
1682 Clusters of richness 1-5, distance 1-6.
Counts in Table 4.2 follow:
This is consistent with a uniform distribution*.
Space Density of Abell Clusters richer than 1:
For uniform distribution, cluster centers
would be 50 h-1 Mpc apart, a factor of ten
larger than that of mean galaxies.
