Left panel: observed PV diagram of the 28SiO (v = 1,   J = 8 → 7) transition, made at a position angle of 115°, with a slit width equal to 1 beam width. The curves represent different rotational regimes: the white curve illustrates a Keplerian trend, the black curve illustrates conservation of angular momentum. Right panel: observed PV diagrams of the 28SiO (v = 1,   J = 8 → 7) transition, made at a position angle of 25°, with a slit width of 0.9′′.
