The scaling relation of early-type galaxies in clusters. II. Spectroscopic data for galaxies in eight nearby clusters.


Abstract (from CDS):

We present low and intermediate resolution spectroscopic data collected for 152 early type galaxies in 8 nearby clusters with z≤0.10. We use low resolution data to produce the redshift and the K-correction for each galaxy, as well as to give their overall spectral energy distribution and some spectral indicators, including the 4000Å break, the Mg2 strength and the NaD equivalent width. We have also obtained higher resolution data for early type galaxies in three of the clusters, to determine their central velocity dispersion. The effect of the resolution on the measured parameters is discussed. A new accurate systemic redshift and velocity dispersion is presented for four of the surveyed clusters, A98, A3125, A3330, and DC2103-39. We have found that the K-correction values for E/S0 bright galaxies in the given nearby clusters are very similar. We also find that the distribution of the line indicators significantly differs from cluster to cluster.

CDS comments: Table 4: numberings 'FNNgN' and 'GNN' are the 'Spectrum id' used in the last column of Table 3, all objects have an identity, so these numberings are not used in SIMBAD.
