Notes.
The rest frequencies of RRLs of C II (Eq. (1)) are listed.
The velocities will be 3.5 km s−1 redder than the values listed here if the rest frequencies of RRL of O II are adopted (Sect. 3). The numbers in brackets in the third to fifth columns represent the uncertainties.
A transition of CH3OCH3 has close frequency but can be reasonably ignored (Fig. 2).
