Spatially resolved spectroscopy of Coma cluster early-type galaxies IV. Completing the dataset

Understand

The long-slit spectra obtained along the minor axis, offset major axis and diagonal axis are presented for 12 E and S0 galaxies of the Coma cluster drawn from a magnitude-limited sample studied before.

• The rotation curves, velocity dispersion profiles and the H_3 and H_4 coefficients of the Hermite decomposition of the line of sight velocity distribution are derived.
• The radial profiles of the Hbeta, Mg, and Fe line strength indices are measured too.
• In addition, the surface photometry of the central regions of a subsample of 4 galaxies recently obtained with Hubble Space Telescope is presented.
