A Catalog of the North-South Visibility Functions of Radio Sources at 1425 MHz


Observations with the North-South interferometer were made in 1966 using the two 90-foot paraboloids at the Owens Valley Radio Observatory to determine the strip-scan distribution in position angle 0° for a large number of extra-galactic radio sources. The frequency of the observations was 1425 MHz. In conjuction with other data taken with an East-West interferometer (Fomalong 1967; hereafter called Paper I) and off-transit data taken in 1966 and 1967, two-dimensional structures can be deduced for the sources. These results will be published elsewhere (small-diameter sources, Fomalont and Moffett 1971; large-diameter sources, Fomalont 1971).

Additional Information

I wish to thank Dr. A.T. Moffet for his assistance in the observation and reduction of the data. Research in radio astronomy is supported by the US Office of Naval Research under Contract N00014-67-A-0094-0008, and the National Science Foundation under grant 15271.
