A comment about the difference between polarization and anisotropy:
Given the definition of polarization and anisotropy, one can show that:
or
Clearly, the information content in the polarization function and the anisotropy function is identical and the use of one term or the other is dictated by practical considerations as will be discussed later.
For example:
0.069
0.10
0.22
0.30
0.40
0.50
