Radial velocities of galaxies in the vicinity of groups of galaxies.
Abstract
New determinations of the radial velocities for 31 galaxies in the neighborhood of groups of galaxies are reported. The observations are described, and data are given for the galaxies in a table, including the number of spectra used, the radial velocity of each galaxy corrected for the motion of the sun and the earth, the internal error in the measurement, estimates of the quality of the spectra, the spectral lines used in the calculation of the velocities, the radial velocities determined by other authors, and the membership of the objects in galactic systems. The data from other authors are used to determine the real (external) accuracy of the present determinations, and good agreement is found.
