Abstract:
We present the final observational data for a spectroscopic study of
a sample of cD galaxy clusters. The goal of this program has been to
study the dynamics of the clusters, with emphasis on determining the
nature and frequency of peculiar-velocity cD galaxies. In this paper
we present redshifts for 762 galaxies in the fields of the rich Abell
clusters A779, A1691, A1749, A1767, A1837, A1927, A2067, A2079, A2089,
A2199, and A2666. We also present preliminary dynamical properties for
these clusters using our measured redshifts.

Note (1): [HO98] ACO NNNN NNN in Simbad
Note (2): The symbols are:
E: the velocity comes from measurements of emission lines only, rather
than the cross-correlation of the absorption spectra
A: presence of absorption in the Balmer series
NM: foreground or background galaxy that is not a velocity member of
the cluster
cD: central cD galaxy. Is followed by the number of repeated
independent observations of the cD redshift
