We made huge progress with the new Kurucz parser (it's almost ready!). As I said last week, this is a difficult task and involves reestructuring different pieces of existing code and some knowledge the atomic structure and physics.
In this notebook you can see a demonstration on how the new GFALL class returns the same DataFrames than the old API. Next step consist in adding metastable flags for lines and levels.
Once this work is completed we should discuss how to move on. Probably we want to automatize the process of making new atomic files: every time a source is updated (for example NIST atomic weights) trigger a new build.
