Notes. Approximate peak positions of the 3 mm continuum emission (see Sect. 3.1) and the three locations of maximal line width of the CH3 C2H 50 → 40 transition, where the first column provides the associated barycentric radial velocity. The positions are close to the midline of the inclined nuclear disk of NGC 4945.
