So, it seems pretty clear that the RecoilAnalysis version is the well-maintained version. I can't even recall doing a migration or in which direction i migrated it. I assume from VubAna->RecoilAna for the introduction of the recoil analysis base class. I'll go through the 2 and bring each up to speed with the other.
