The raman option includes single order rotational Raman scattering in the calculation. The solution treats Raman as a perturbation similar to the approaches of Vountas et al. (1998) and Spurr et al. (2008).

The raman option may only be used for spectral calculation.

A special radiative transfer solver, qdisort, is needed to solve the radiative transfer equation including Raman scattering. This solver is automagically invoked when specifying the raman option. It is thus not neccessary to set the rte_solver.

Please note that while the raman option has been extensively tested and verified, it is nevertheless a new option, hence, use it with care. Also it is not optimized for speed. It is thus computationally very expensive. Major speedups are planned for future releases.
