The final polarization parameters are usually presented graphically in
the form of a polarization map (see the first page of this document
for an example). Each measurement is represented as a vector parallel to
the plane of polarization. The length of the vector is proportional to
the degree of polarization, which varies from 0% to 100%. The Stokes
vectors can be binned to reduce the number of vectors in the map to a
manageable number. The map is often overlayed on a total intensity image
or contour map of the object to emphasize any correlation between the
visual appearance of the object and the morphology of the polarization
map.
