Computes the background radiation.

This method checks the back of the ray path and calls spectral_rad_space_agenda and spectral_rad_surface_agenda as needed.

If the back of the path is still in the atmosphere, an error is raised. As is it if the background position is unknown.

Tip

To access subsurface emission, the spectral_rad_surface_agenda must be able to handle subsurface emission. It will likely need the surface emission agenda as well, but that would be circular. Therefore, please consider using spectral_rad_closed_surface_agenda to compute the surface emission without invoking recursion.
