Abstract

Radial distances, linear dimensions, and total luminosities are given for 24 identified extragalactic radio sources, 19 of which have measured radial velocities. Using the synchrotron theory, the total energy and magnetic-field strength required to account for the observed luminosity are estimated for each source. Eight sources are found with energy requirements exceeding 1060 ergs. Typical field strengths are 10- oersted. The linear diameters range from less than 1 to 290 kpc. Illustrations of the radio and optical brightness distributions are given for 11 sources.
