Redshifts of a sample of distant Abell clusters
Listed in IVOA Registry (Virtual Observatory)
We have measured redshifts for a complete sample of 145 Abell clusters of galaxies.
Description
The sample covers a 561 square degree region at high Galactic latitude. The median redshift of the clusters in the sample is 0.16.
For R >= 1 clusters the correlation length is r_0_ = 21 h^-1^ Mpc. The amplitude of the correlation function is a factor of 1.4 less than that obtained by Bahcall and Soneira, but the difference is within the 1 {sigma} uncertainties. In this sample we cannot detect clustering on scales >~ 70 h^-1^ Mpc.

Although the maps of the cluster distribution in redshift space show a large void of diameter ~20,000 km s^-1^, frequent occurrence of such large empty regions is consistent with the smaller scale behaviour of the correlation function of the survey. Large-scale peculiar motions are <~1000 km s^-1^. This limit is inconsistent with the claim of detection by Bahcall, Soneira, and Burgett of ~2000 km/s peculiar motions.
We suggest that the earlier result is affected by the Corona Borealis supercluster, which contributes more than a third of the excess pairs in the shallower survey.
