So this is the so-called Vatican tonary (first part of Palatina 1346). It looks like an appendix of Codex Calixtinus. I wonder, what you will make of it... (see Chr. Meyer's edition).
Concerning Aurelianus, I like the Byzantine intonation names AIANEOEANE (f. 46v) and NANA ANNES (f. 48v)—like tritos and varys echemata in one—, you will not find them in F-VAL 148.
Wonderful that Vatican manuscripts are now being digitised.
