Abstract:
We present a spectroscopic survey of the rich X-ray-selected galaxy
cluster CL 1358+6245 at z=0.328. When our 173 new multislit spectra of
cluster galaxies are combined with data from the literature, we
produce a catalog of 232 cluster members in a region 10'x11'
(3.5Mpcx3.8Mpc) surrounding the brightest cluster galaxy. These data
are used to study the structure and dynamics of the cluster and to
examine the radial and velocity distributions as a function of
spectral type. We classify the spectral types of the cluster members
according to the strengths of the Balmer absorption lines (Hδ,
Hγ, and Hβ) and the [O II] 3727Å emission line.

Note (1): Positions are given with respect to the brightest cluster galaxy
(number 375) at 13:58:20.7s+62:45:33 (1950), with
positive x to the west and positive y to the north.
Note (2): The strength of each spectral index is a measure of the flux in the
central bandpass compared to a continuum level set by the sidebands.
