Abstract

The dependence of the degree of linear polarization of the radiation from 213 extragalactic sources on galactic coordinates was investigated at 21-centimeter wavelength. In addition to the previously known latitude effect, the depolarization of the radiation during transit through our galaxy is also a function of galactic longitude. One possible explanation is that galactic depolarization is a simple function of the distance traveled by the radiation through an extended galactic halo.
