Abstract
Using the full magnetoionic theory in the microwave region along a ray-path through the solar chromosphere and corona we have obtained a convenient expression, and from it a simple diagram which permits the direct computation of the brightness temperature and circular polarization from a thermal source, for any combination of the physical parameters which enter in their computation.
