A Survey of the Integrated Radio Emission at a Wave-Length of 3.7 m

A survey of the integrated radio emission between declinations −28° and +82° has been made at a wave-length of 3.7 m using an aerial having beam-widths to half power of $$\pm{1}^{\circ}\times\pm7\frac{1}{2}^{\circ}$$. Except in areas very close to the galactic plane where the resolving power of the aerial is insufficient to show the fine structure of the galactic radiation, the values of brightness temperature are believed to be accurate to within 15 per cent. The results can be interpreted in terms of three symmetrical components extending to progressively greater distances from the plane, as well as some interesting irregular features.
