Notes. The relative positional offset in Cols. 3 and 5 is obtained with respect to the reference spot (ID 53 marked by an asterisk), whose absolute coordinates are [α(J2000.0) = 22h56m17s.9042, δ(J2000.0) =  +62°01′49″.577]. Proper motions are measured relative to the maser barycenter (see Sect. 3.2).
