Workspace Method specular_losCalcNoTopography

Description

Calculates the specular direction of surface reflections for horisontal
surfaces.

In contrast to specular_losCalc, this method ignores the topography
implied by z_surface. That is, any slope of the surface is ignored.

The typical application of this WSM should be water surfaces (lakes and
oceans).
