OBSERVATIONS OF THE CALIFORNIA INSTITUTE OF TECHNOLOGY RADIO OBSERVATORY, OWENS VALLEY, CALIFORNIA 1961. 4. BRIGHTNESS DISTRIBUTION IN DISCRETE RADIO SOURCES. I. OBSERVATIONS WITH AN EAST-WEST INTERFEROMETER
Abstract
The Caltech variable baseline interferometer was used in a program of brightness distribution measurements on 195 discrete radio sources at a wavelength of 31.3 cm. This paper reports measurements, made with an east-west interferometer baseline, of the complex visibility functions of 127 sources. The amplitude and phase of the visibility functions were measured at transit with antenna spacings of 195, 389, 779, and 1557 lambda. Using these same basic spacings, and by observing at large hour angles, the visibility amplitude was measured at ten other effective spacings between 126 lambda and 1363 lambda. Not all sources were observed at all spacings. The data are presented in tabular form, and graphs of the visibility amplitude as a function of antenna spacing are given for 51 of the more interesting sources.
