RT4CalcWithRT4Surface

As RT4Calc except for using RT4’s proprietary surface type handling.

This WSM is only indented for testing purposes.

The following surface type/property methods are available and require the the following input:

‘L’ambertian: surface_scalar_reflectivity, surface_skin_t
‘F’resnel: surface_complex_refr_index, surface_skin_t
‘S’pecular: surface_reflectivity, surface_skin_t

‘L’ and ‘F’ use proprietary RT4 methods, ‘S’ uses RT4’s Fresnel methods modified to behave similar to ARTS’ surfaceFlatReflectivity().
