Help for PHO_HAPKE_HG1_DOM


PURPOSE:

In this PDF, the user is asked for the only parameters needed for the 
Hapke-1986-one-term-Henyey-Greenstein photometric function containing the
coherent backscattering term in the form of Dominique 1992.


MATHEMATICAL BACKGROUND :


bidirectional reflectance [1/str] :

r(i,e,g) = ...
