Abstract:

We present the results of spectroscopic observations of galaxies in a sample of nearby clusters. We measured galaxy redshifts and estimated cluster velocity dispersions. These observations were carried out at the Observatoire de Haute Provence as part of a program aiming at a more detailed study of the Cluster Fundamental Plane.
