Empirical Lunar Lambert photometric model Derive model albedo using phase dependent Minnaert equation and calculated empirically.
Limb-darkening k and phase function are arbitrary polynomials in phase angle.
Where k is the Minnaert index, an empirical constant (called nu in Hapke)
If k (nu) = 1, Minnaert's law reduces to Lambert's law. See Theory of Reflectance and Emittance Spectroscopy, 1993; Bruce Hapke; pg. 191-192.

void Isis::LunarLambertEmpirical::SetPhotoLList | ( | PvlKeyword | lstrList | ) |
Set the empirical Lunar Lambert function L exponent list.
This is used to govern the limb-darkening in the Lunar Lambert photometric function. Values of the Lunar Lambert exponent generally fall in the range from 0.0 (Lambert function) to 1.0 (Lommel-Seeliger or "lunar" function). There are no limits on the value of this parameter, but values far outside the 0 to 1 range will not be very useful.
