Abstract

We present long slit spectra for a magnitude limited sample of 35 E and S0 galaxies of the Coma cluster. The high quality of the data allowed us to derive spatially resolved spectra for a substantial sample of Coma galaxies for the first time. From these spectra we obtained rota- tion curves, the velocity dispersion profiles and the H3 and H4 coefficients of the Hermite decomposition of the line of sight velocity distribution. Moreover, we derive the radial line index profiles of Mg, Fe and Hβ line indices out to R ≈ 1re − 3re with high signal-to-noise ratio. We describe the galaxy sample, the observations and data re- duction, and present the spectroscopic database. Ground- based photometry for a subsample of 8 galaxies is also presented.
