Meanings
-
(not-comparable) With respect to the centre of a galactic group
The velocity dispersions of early- and late-type galaxies in compact groups change little with groupcentric radius; the radii sampled are less than 100~h#123;-1#125; kpc, smaller than the radii typically sampled by members of massive clusters of galaxies.
