Scientific paper

Radio observations are reported for 57 quasars. Included are all of the quasars of Schmidt's 1974 complete sample from the 4C catalog. The observations were made with the Green Bank interferometer at 2.7 and 8.1 GHz, with baselines ranging from 300 m to 35 km. Model brightness distributions are presented, consisting of one to four elliptical Gaussian components. Angular sizes range from less than 0.2 to 77 arcsec. Of 38 well-resolved sources 21 contain a compact central component coincident with the optical object. The quasar 4C 32.69 = 2349+328 appears to exhibit a jetlike structure connecting the central component to one of the outer lobes.
