Update data for recombination lines
The AtomNeb database described in this paper:
http://joss.theoj.org/papers/10.21105/joss.00898
contains recombination data for C II, N II, O II, and Ne II. It lists a number of papers, mostly before 2000, on recombination producing first ions then say that their collection is "compiled based on the atomic data in MOCASSIN." Updating the recombination rates for these elements has been on the wish list for some time. We could start with this list and complete the literature survey for the more recent papers Pete Storey has done.
