Abstract:
We study the dynamical status of the poor, low X-ray luminous galaxy
clusters Abell 610, Abell 725, and Abell 796 (at z=0.1, 0.09, and
0.16, respectively), containing diffuse radio sources (relic, relic,
and possible halo, respectively).
Our analysis is based on new spectroscopic data obtained at the
William Herschel Telescope for 158 galaxies, new photometry obtained
at the Isaac Newton Telescope with the addition of data recovered from
the Data Release 5 of the Sloan Digital Sky Survey. We use statistical
tools to select 57, 36, and 26 cluster members and to analyze the
kinematics of cluster galaxies, as well as to study the 2D cluster
structure.
Description:
We carried out multi-object spectroscopic observations of A610, A725,
and A796 in November 2004 and January 2005. We used AF2/WYFFOS, the
multi-object, wide-field, fiber spectrograph working at the prime
focus of the 4.2m William Herschel Telescope (WHT, Island of La
Palma, Spain).

Global Notes:
Note (G1): In Simbad, the galaxy are designated as [BBG2008] ACO NNN NNN
where the first 3-digit number indicates the Abell cluster number
(610, 725, 796 for tables 1, 4, 5 resp.), and the second 3-digit
number is the Sequential number of galaxy.
Note (G2): Notes as follows:
i = non-cluster galaxy
b = first and second brightest galaxies of the cluster
