Help for PHO_REGNER_HAPKE_HG1


PURPOSE:

In this PDF, the user is asked for the only parameters needed for the
combined photometric function of the system atmosphere/surface as proposed by 
P.Regner. 


MATHEMATICAL BACKGROUND :

The approximation from Van Blerkom for the atmosphere is combined with the 
Hapke-1986-one-term-Henyey-Greenstein photometric function for the surface.


bidirectional reflectance [1/str] :

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