Review of the NLTE emissivities code comparison virtual workshop
TLDR
In this article, the first "virtual workshop" designed to compare NLTE emissivities produced by widely differing types of atomic physics codes is presented, and a small set of significant results illustrate the progress that is still to be achieved.Abstract:
We review the first “virtual workshop” designed to compare NLTE emissivities produced by widely differing types of atomic physics codes. A small set of significant results, illustrating the progress that is still to be achieved, is presented. We conclude with some lessons learned and possible avenues for future progress.read more
