This project is built upon the work of many researchers in many fields. For citations to (astro)physics and (astro)statistics literature, please see the technical documents pointed to in the Citation section. Moreover, we point to the bibliograpy of Riley et al. 2019 as the first published application of the X-PSI package, and to the ApJL Focus Issue of which this article is a member.
