EIRENE can calculate H-alpha emission due to atomic and molecular processes. Here, molecular processes are the dissociation of hydrogen molecules and molecular ions with the production of atoms in excited states. Such atoms are not taken into account in the ADAS collisional radiative model. Moreover, the atomic-only component of H-alpha emission calculated with EIRENE is usually 1.5 - 2 times higher (at least in the EIRENE versions for SOLPS) than the excitation + recombination emission calculated with ADAS. This difference is likely due to the difference in hydrogen data in EIRENE and ADAS.
I would like to have the molecular-only and total (atomic + molecular) H-alpha emissivities as SOLPSSimulation attributes, so that they can be used to calculate H-alpha intensities bypassing the standard Cherab methods, which are based on the ADAS data.
Since I needed this feature for my work, I already implemented it in a dedicated branch. I'll make a PR, so you can view the changes.
