Abstract:
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.
Description:
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.
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.
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.
