An extensive redshift survey has been conducted on a sample of 15 nearby () 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 0.2-0.8 Mpc (H0 = 50 km Mpc-1) 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 5 km and an overall consistency of the measurements and their uncertainties. We estimate our redshifts to have mean random errors around 30 km . A population analysis of the clusters will be given in a forthcoming paper.
