Notes. (1) Number of member galaxies for which the position in the sky, velocity along the line of sight, and stellar mass are available. (2) Average cluster redshift z, based on the values of the redshift of the selected member galaxies. (3) Adopted eccentricity, as defined in the text (see Sect. 3). (4) Global velocity dispersion, based on the velocity distribution shown in Fig. 2. (5) Total stellar mass M⋆, tot associated with the distribution illustrated in Fig. 3. (6) Virial mass M200 and (7) virial radius r200, taken from Sartoris et al. (2020) for AS1063 and from Biviano et al. (2013) for M1206. (8) Half-mass radius Rhm, defined as the circularized radius that encloses half of the stellar mass projected on the sky. (9) Relaxation time TD, as defined in Eq. (1).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
