Abstract:
We present the initial results of a spectroscopic study of a sample of
cD galaxy clusters. The goal of this program is 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 611 galaxies in the fields of the rich Abell clusters A193, A399,
A401, A1795, A1809, A2063, and A2124. We discuss our data reduction
techniques, and compare our derived velocities with previously
published values. We find a frequency of emission line galaxies of
∼6% in clusters, a factor of 2-3 less than the field.

49- 86 A38 --- Com Comments (1)
--------------------------------------------------------------------------------
Note (1):
A letter "E" in the comments field means that the velocity was derived from
emission lines only.
For galaxy 388 in table4, the listed velocities were derived from emission
and absorption lines separately.
The letter "A" indicates the presence of absorption lines in the higher
Balmer lines.
The number of independent measurements contributing to the combined velocity
of the cD are also reported.
The identifying number of each cD galaxy is 201, except for the A399 cD
which is 448 in table4
