The second column shows the number of spectroscopically confirmed members in each clump. Redshifts (3rd column) and velocity dispersions (4th column) are estimated with the biweight estimator (Beers et al. 1990). The redshift errors are estimated by bootstrapping, taking into account individual redshift errors. The 5th and 6th columns show the Virial radii and masses (Carlberg et al. 1997). The last column shows the probability that each clump is dynamically bound to RDCSJ1252. The galaxies in clump2a are not spatially concentrated, suggesting that this clump probably not a bound system. There are only two members in clump 4 and the redshift is an average redshift of these two galaxies. The properties of RDCSJ1252 are added for reference. See text for details.
