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).

(*)

Fossil system according to our definition.

(**)

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.

(a)

System with not reliable membership determination for which we did not compute σv and Mv.
