Notes. Column (1): system number as in Santos et al. (2007); Col. (2): right ascension of the BGG; Col. (3): declination of the BGG; Col. (4): redshift of the BGG; Col. (5): gap in magnitude between the two brightest member galaxies; Col. (6): gap in magnitude between the brightest and the fourth brightest member galaxies; Col. (7): estimation of the virial radius of the system derived from LX; Col. (8): number of velocities available within R200. The number of new velocities from our own observations is given in parenthesis; Col. (9): number of spectroscopically confirmed members; Col. (10): velocity dispersion of the system; Col. (11): mass of the system within 0.5 R200, from Eq. (4).
For homogeneity, we recomputed the gaps for this system that we analyzed in Aguerri et al. (2011). In particular, we used 0.5 R200 and only three different magnitudes to calculate Δm12 and Δm14.
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.
Initial download of the metrics may take a while.
