Description:
An extensive redshift survey has been conducted on a sample of 15
nearby (0.01≲z≲0.05) clusters of galaxies. A total number of 860
redshifts were determined by fitting of emission-lines and/or
cross-correlation techniques. Of this sample, 735 galaxies are within
0.2-0.8Mpc (H0=50km/s/Mpc) of the center of clusters. Approximate
morphological types are available for most of the galaxies. A
comparison of the present redshifts with published data allows an
extensive error analysis. The agreement is excellent with the most
modern data, showing a zero point error of 5km/s and an overall
consistency of the measurements and their uncertainties. We estimate
our redshifts to have mean random errors
around 30km/s. A population analysis of the clusters will be given in
a forthcoming paper.
