Extended Data Figure 2

Velocity of 13CO (a), and C18O (b) versus position, using an inclination angle of 55°. The dashed curve is indicative of Keplerian rotation around a 0.4Msun star. The red and blue colours indicate the redshifted and blueshifted components, respectively. Error bars show the standard deviations of the Gaussian fits in position and the velocity resolution. au, astronomical units.
