Scientific paper

Radial velocity data on 414 galaxies in the Coma region and of statistical membership are used to determine the virial mass of the Coma cluster and discuss several issues in its kinematics. Analysis shows that the Coma cluster has undergone some dynamical evolution and has not yet reached a sufficiently relaxed state. Judging by present available data, mass segregation is not marked.
