Abstract
We report the results of the first multi-object
spectroscopic observations at the Danish 1.54 m telescope at
La Silla, Chile. Observations of five cluster candidates from the ESO Imaging
Survey Cluster Candidate Catalog are described. From these
observations we confirm the reality of the five clusters with measured
redshifts of
. We estimate velocity dispersions in
the range 294-621 km s
-1 indicating rather poor clusters. This, and the
measured cluster redshifts are consistent with the results of the matched
filter procedure applied to produce the Cluster Candidate Catalog.
Key words: cosmology: observations -- galaxies: distances and redshifts -- galaxies: clusters: general
