Abstract
We present minor axis, offset major axis and one diagonal long slit spectra for 10 E and S0 galaxies of the Coma cluster drawn from a magnitude-limited sample studied before. We derive rotation curves, velocity dispersion profiles and the H₃ and H₄ coefficients of the Hermite decomposition of the line of sight velocity distribution. Moreover, we derive the line index profiles of Mg, Fe and H line indices and assess their errors. The data will be used to construct dynamical models of the galaxies and study their stellar populations.

Key words: galaxies: elliptical and lenticular, cD -- galaxies: kinematics and dynamics -- galaxies: stellar content -- galaxies: abundances -- galaxies: formation
