JOSS paper for Paper 2?

[gully]

It is possible to submit a JOSS paper alongside an AASJournals paper (e.g. an ApJ or AJ paper). There's a blog post about it here: https://blog.joss.theoj.org/2018/12/a-new-collaboration-with-aas-publishing

We could/shoulfd consider either this joint path, or a standalone JOSS paper. This way, @SujayShankar2001 could put some of the more technical code-specific aspects into the JOSS paper, and then the more scientific astronomy-specific aspects into the ApJ paper. Just a thought!
