The distribution of the galactic diffuse radio background

The distribution of the galactic radio emission is analyzed and a three component model (Halo, Base Disk and Spiral Arms) of the observed radiation examined.To reach agreement between temperature measured at low and high galactic latitudes we need: (a) a low emissivity spherical halo, (b) the Sun inside the local spiral arm somewhere between the arm axis and the arm outer edge, and (c) free circulation of the radiating electrons between the three emitting regions.
