				<para>
   All velocities are heliocentric and in km/s. vz1 are reliable velocities
   (based on the cross-correlation peak) while vz2 are velocities which may be
   based on the wrong CCF peak altogether. The dividing line between C1 and C2
   was taken to be a Tonry and Davis "r" value of the cross-correlation
   function of 3.5.</para><para>   The velocity errors for vz1 were calculated using a best-fit solution of
   error vs Tonry and Davis "r" value. This curve was calibrated using
   redundant observations. The vz2 and unmeasured velocities have a 300 km/s
   error. This is conservative IF the correct CCF peak was chosen.</para><para>   This file includes 512 objects identified after Batuskis initial search,
   plus some of Batuskis which didn't seem to match any of the 512 (these have
   4-digit ids). Four are from the literature and also did not seem to
   match the author's positions. They are labeled, S, Z, or L.</para></description>
				<abstract>
					<para>
   Velocities are presented for 254 galaxies in the rich Abell cluster 2634.
   Positions are given for 274 additional galaxies for which further
   investigation is desirable.</para></abstract>
