Shapley Concentration of galaxies redshift survey
Description
This dataset gives results from a galaxy redshift survey of the Shapley Concentration (SCl 124), the richest nearby supercluster of galaxies centered around (RA,Dec) = (13h25m, -30d). It includes ~40 Abell rich clusters as well as regions with low galaxy densities (voids). See http://en.wikipedia.org/wiki/Shapley_Supercluster. The dataset, based on the redshift survey of Drinkwater et al. (2004), has 4215 galaxy redshifts with uncertainties) in addition to celestial locations and visible magnitudes. The sample is described in Appendix C.5 of Feigelson & Babu (2012). It is useful for study of 3-dimensional spatial point processes with high-amplitude, anisoptropic spatial clustering.
