Source and rsigns from LH83. The Gregofacsimil Invitatoriale has an identical tone as 6f2 first variant.
Removed some episemata, straying from LH83, in cases where some verses bear one but not others, with no prosodic explanation
Removed some dim.liqs where the vowel is fully voiced on the second note: the liq.dim was signaling no modification in the execution and had no reason to be kept.
