Circular Polarization Measurements of Compact Radio Sources at 1420 Mhz. Interferometric Observations of the Radio Source Vro 42 22 01

摘要

The circular polarization of seventeen small-diameter radio sources has been measured at a frequency of 1420 MHz. None had detectable polarization, although for some sources independent measurements made at different frequencies agreed as to the sense of circular polarization. The position of VRO 42 22 01 has been measured to an accuracy of 2 in. Its diameter at 9.6 GHz is
