Help for PHOTFIT2_MOSHER

PURPOSE:

In this PDF, the user is asked for the parameters and there limits needed to 
fit Mosher's photometric function.
If a sulution guess falls out-of-bonds then the attemp will be aborted and 
a new guess attempted.

MATHEMATICAL BACKGROUND :

bidirectional reflectance [1/str] :

r(i,e,g) = (A + B * g  C * exp(- D * g)) * pow(cos(i) * cos(e), MO_EXP1 + MO_EXP2 * g) / cos(e)

with:
i 	incidense angle
e 	emission angle
g 	phase angle 
A 	A_VEVERKA
B 	B_VEVERKA
C 	C_VEVERKA
D 	D_VEVERKA
