Notes. Columns: (1) Name of the region. For each cluster, the first line corresponds to the circle of radius R200. The last line is the main body of the cluster, i.e. the principal KMM partition. (2) Background-subtracted number of red-sequence galaxies belonging to the region, normalised to the value obtained within R200. (3) Associated R-band luminosity, corrected from an average background contribution and normalised by its value within R200. (4) Fraction of red-sequence galaxies. (5) R-band magnitude of the brightest red-sequence galaxy. (6) Projected separation between the region centre and the cluster centre, in unit of R200. (7) Number of spectroscopic members associated with the corresponding KMM partition, limited within R200 for the R200 and MB regions. (8) Rest-frame velocity. (9), (10) Line-of-sight velocity dispersion, and the third power of its ratio to the dispersion within R200. The latter quantity can be used as a relative mass estimator, assuming a scaling M ∝ σ3. We note that the σ200 are different from the values from Table 3, since here we used the R200 derived from the virial estimator applied to the red galaxies (see Sect. 4.1). (11) Probability that the structure is bound to the main body, according to the Newtonian criterion. Regions for which a significant X-ray counterpart was detected are indicated by a (†).
