OBSERVATIONS OF THE CALIFORNIA INSTITUTE OF TECHNOLOGY RADIO OBSERVATORY, OWENS VALLEY, CALIFORNIA 1961. 5. BRIGHTNESS DISTRIBUTION IN DISCRETE RADIO SOURCES. II. OBSERVATIONS WITH A NORTH-SOUTH INTERFEROMETER

Abstract

The brightness distribution in 165 radio sources was obtained at a wavelength of 31.3 cm. The measurements were made with the variable spacing interferometer at the Owens Valley Radio Observatory using a north-south baseline. Primary sets of observations, giving the visibility amplitude and the phase, were taken at transit at four different antenna spacings. Additional information about the brightness distribution was obtained from observations at large hour angles, using the same physical antenna separations. The results of the observations are given in tabular form and several visibility curves are shown. (Author)
