Abstract
This paper describes a survey of the sky for a linearly polarized component of the galactic radio emission. The observations were made at the frequency of 408 Mc/s with an aerial beamwidth of 8 degrees between half power points. The survey includes all the sky between δ = − 7°.5 to δ = 90°, observed in declination strips separated by 7°.5. The observations have been corrected for the spurious contributions from regions of sky outside the main beam. In the final analysis the position angles of the confirmed polarization vectors are corrected for the effects of the Faraday rotation in the ionosphere. It is believed that linearly polarized emission greater than 0.8 °K in magnitude could be detected with the polarimeter used in the observations. Thus a low upper limit is set for the regions of sky where no linearly polarized radiation has been observed. In two regions the polarization brightness temperature reaches 2–4 °K.
