Density contrasts, masses, and radii of the core and the outskirts regions of the A2142 supercluster.
Notes. Columns are as follows: (1): Global luminosity density D8 of the regions (in units of mean luminosity density, ℓmean = 1.65 × 10-2). Main body of the supercluster is defined as D8 ≥ 5, without group regions 2 and 3. Main+env denotes main body of the supercluster without group regions 2 and 3, but with local neighbourhood of the main body; see text for details); (2): the total dynamical mass of groups (in case of groups with 2 and 3 member galaxies we use median mass); (3): the total estimated mass of a region (including faint groups and intracluster gas, see text); (4): radius of the region (in h-1 Mpc); (5): density contrast of the region according to the dynamical mass; (6): density contrast of the region according to the estimated mass.
