The 1.49 GHz continuum emission from 161 spiral galaxies was mapped. The correlation of radio continuum and NIR surface brightnesses for a given Hubble type indicates a connection between radio continuum emission and the overall stellar populations of normal spiral galaxies. The intrinsic range of both the radio continuum emission and the hybrid H magnitude surface brightness in spiral galaxies suggests the existence of a wide intrinsic range of the stellar population at a given Hubble type or rotation velocity in spiral galaxies. 17 references.
