Description:
The Southern Sky Redshift Survey (SSRS) includes 13 groups of 5 or
more members with velocities ≥2000km/s. By measuring redshifts and
accumulating data from the literature, we increase the total number of
known group members from 89 to 218. We also measured new redshifts for
59 foreground/background galaxies superimposed on the group
neighborhoods. The velocity dispersions of the groups are remarkably
stable.
