Detailed Description

Lunar (Lommel-Seeliger)-Lambert law photometric model Derive model albedo for Lunar (Lommel-Seeliger)-Lambert law.

Phase independent and calculated analytically. Lommel-Seeliger law:

Reflectance=1/(1+cos(E)/cos(I))

Where: E=the angle between the observer and the slope normal I=the angle between the sun and the slope normal

void Isis::LunarLambert::SetPhotoL

(

l

[virtual]

Set the Lunar-Lambert function weight.

This is used to govern the limb-darkening in the Lunar-Lambert photometric function. Values of the Lunar-Lambert weight 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.

Parameters:

l

Lunar-Lambert function weight, default is 1.0
