public class IsotropicRadiationClassicalConvention extends Object implements RadiationSensitive
This model uses the classical thermo-optical coefficients Ca for absorption, Cs for specular reflection and Kd for diffuse reflection. The equation Ca + Cs + Cd = 1 always holds.
A less standard set of coefficients α = Ca for absorption and
τ = Cs/(1-Ca) for specular reflection is implemented in the sister
class IsotropicRadiationCNES95Convention
