Using both codex and supplement. Question regarding pfp!

So I'll be Hsiang the codex real space raiders detachment and the supplements formation with haemy and wracks. Here's my question:

Do the units from real space raiders use the regular table, and do units from the formation use the supplements table? Ie referencing two tables in one game? Thanks!

Yes, each detachment uses the PfP table that applies to that detachment.
