ADC_Keywords: Surveys; Clusters, galaxy; Redshifts Keywords: galaxies: clustering-galaxies: distances and redshifts Abstract: We have measured redshifts for a complete sample of 145 Abell clusters of galaxies. 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 r0 = 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 σ 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. Notes: Some errors have been corrected. See notes of "table2". File Summary:

Notes: (1) Due to the different origin of the data in columns m1 and m10, it may occur (as for A1124) that m1 > m10. (2) Zeroes in the rightmost decimal digit were removed for m1, m10 and Zest.

Postman (5) This column entry appeared as the headline of each paragraph for one cluster in the published version. (6) In some cases the galaxy is associated with two galaxy clusters indicated as 'A1283/9 and A1289/3'. Note that the published version incorrectly states A1283/8 and A1289/8.
