Fig. 14
Keplerian velocity as a function of radius, r, from the central object for 10, 15, and 20 M⊙. The projection corrected velocity determined from the 334.42 GHz CH3OH vt = 1 line is marked as a grey horizontal line. The grey shaded area corresponds to the projected distance range for the position of the CH3OH vt = 1 spots.
