Workspace Method specular_losCalc
Description
Calculates the specular direction for intersections with the surface. A help method to set up the surface properties. This method calculates specular_los, that is required in several methods to convert zenith angles to incidence angles. The method also returns the line-of-sight for the surface normal.
