Abstract : Observations with a 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 degrees for a large number of extragalactic radio sources. The frequency of the observations was 1425 MHz. In conjunction with other data taken with an East-West interferometer (Fomalont 1967) 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 Moffet 1971; large-diameter sources, Fomalont 1971). The list of the North-South visibility functions is given here. Only the large diameter sources (>60 seconds) are included. The visibility functions for the small-diameter sources can be inferred from the North-South diameter or the diameter limit given in Fomalont and Moffet (1971). (Author)
