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

◆ SetPhotoL()

void Isis::LunarLambert::SetPhotoL ( const double 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

Reimplemented from Isis::PhotoModel.

Definition at line 31 of file LunarLambert.cpp.

Parameters

standard True if standard conditions are used.

Returns true if standard conditions are used, i.e., if SetStandardConditions(true) has been called. This is initialized to false in the constructor.
