Workspace Method irradiance_fieldFromRadiance
Description
Calculate the irradiance also known as flux density from the radiance_field . by integrating over the angular grids according to the grids set by AngularGridsSetFluxCalc See *AngularGridsSetFluxCalc to set *za_grid, aa_grid, and za_grid_weights*
