East-West Fourier Transforms of Polarization Parameters of Radio Sources at 1418 MHz

Abstract

As part of a continuing study employing the Owens Valley Radio Observatory's twin-element interferometer to provide high angular resolution measurements of the various radio source properties (see, especially, Maltby and Moffett 1962; Morris, Radhakrishnan, and Seielstad 1964b; Seielstad 1967; Fomalont 1968), we have measured the Fourier transforms of the distributions of the Stokes parameters Q, U, and V at several antenna spacings along an east-west baseline. The present paper catalogs these measurements, while a subsequent paper will interpret them in terms of the structure of the polarized radiation along a circle of constant declination. We have already published a list of upper limits to the degree of circular polarization in the integrated radiation from several of these sources (Seielstad and Weiler 1968a), as well as a complete analysis of four supernova remnants (Seielstad and Weiler 1968b).
