Et in servis suis dominus miserebitur

There are a couple of scribal mistakes after this antiphon. The antiphon is followed by the rubric 'a' (for antiphon) but instead, we would expect here the rubric 'ps' (for psalm).

The rubric 'a' is followed by the incipit 'adtende clm' which I argue should correspond to the psalm incipit 'audite celi', commonly found in numerous sources already indexed in Cantus (see here).  In PEM database we can read the psalm incipit 'audite celi' placed after the antiphon Cantus ID 002705 in P-BRs MS 032 fol. 116r.
