J/A+A/395/753      Spectroscopy of Coma early-type galaxies. II. (Wegner+, 2002)

Spatially resolved spectroscopy of Coma cluster early-type galaxies. II. The minor axis dataset. Wegner, G., Corsini, E.M., Saglia, R.P., Bender, R., Merkl, D., Thomas, D., Thomas, J., Mehlert, D. <Astron. Astrophys. 395, 753 (2002)> =2002A&A...395..753W
ADC_Keywords: Clusters, galaxy ; Spectroscopy ; Velocity dispersion Keywords: galaxies: elliptical and lenticular, cD - kinematics and dynamics - stellar content - abundances - formation 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 Hbeta line indices and assess their errors. The data will be used to construct dynamical models of the galaxies and study their stellar populations. Description: Table 3 (table3.dat) gives spatially resolved kinematic parameters (v, σ, H3, H4) for the sample galaxies as well as Table 4 (table4.dat) gives their measured line indices (Hβ, [MgFe], <Fe>, Mgb, Mg2).
