ADC_Keywords: Clusters, galaxy; Redshifts Keywords: galaxies: clustering-galaxies: distances and redshifts Descriptions: (Abstract of the paper) We have acquired redshifts for a complete sample of 351 Abell clusters with tenth-ranked galaxy magnitudes (m10) less than or equal to 16.5, including 115 entirely new cluster redshifts. The survey includes all such clusters which lie north of δ=-27deg30arcmin and is the largest magnitude-limited redshift survey of rich clusters to date. Analysis of the spatial distribution of these clusters reveals no clustering on scales larger than 75h-1Mpc; we do not detect the large supercluster complexes reported by Tully. The correlation length is 20.0(±4.3)h-1Mpc, consistent with the results from other surveys. The frequency of voids with radii of order 60h-1Mpc or less is consistent with the form and amplitude of the observed two-point correlation function. There is no significant difference between the clustering properties of RC = O and RC ≥ 1 clusters. A percolation analysis yields 23 superclusters, 17 of which are new. The superclusters are not significantly elongated in the radial direction; large-scale peculiar motions are of order 1000 km s-1 or less. Dramatically new constraints on the large-scale cluster distribution will require surveys an order of magnitude larger. File Summary:

Notes (1): Note that due to the different origin of the data, m1 can be higher than m10 (e.g. for A1892). Moreover, the magnitude scale for northern clusters (A1-A2712) is different from that for the southern clusters (A>2712). Trailing zeroes in m1, m10 and Zest were truncated at CDS.
