Ah no worries, thanks. I just finished gathering the last of the guardian mats for the 4 new modules. Was a lot of work, but very doable with concentration.
You only need 42. And you are better off heading to either the third site which has 4 closely distributed obelisks, or heading to one of the old sites and parking in front of a single obelisk until you get everything you need. The epsilon data is probably the slowest thing to collect, but it can be done in a single session.
Just FYI, the new sites boot you out to the perimeter if you instance swap. The old ones let you park in front of an obelisk and swap all day.
I went to the Ancient Ruins at COL 173 Sector QU-O D6-25 (-36.6 / -158.2), got my 42 Epsilon patterns in a bit less than two hours. I think I scanned all the obelisks on that site five times before I got what I needed.
