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.
