Abstract: The long-slit spectra obtained along the minor axis, offset major axis anddiagonal axis are presented for 12 E and S0 galaxies of the Coma cluster drawnfrom a magnitude-limited sample studied before. The rotation curves, velocitydispersion profiles and the H 3 and H 4 coefficients of the Hermitedecomposition of the line of sight velocity distribution are derived. Theradial profiles of the Hbeta, Mg, and Fe line strength indices are measuredtoo. In addition, the surface photometry of the central regions of a subsampleof 4 galaxies recently obtained with Hubble Space Telescope is presented. Thedata will be used to construct dynamical models of the galaxies and study theirstellar populations.
