Is the Milky Way "Rotation Curve" Real?

Indications of an Unmodelled Component in Spectrographic Measurements of Local Stars
The Milky Way's rotation curve appears to be flat, based on the measured doppler shifts of interstellar gas. In contrast, the authors find that the rotation curve of the motions of local stars is not flat. Is the explanation an unmodelled component to the spectrographic measurements?
