Moment zero maps for C¹⁸O J = 2 – 1 (top), ¹³CO J = 2 – 1 (middle), and ¹²CO J = 2 – 1 (bottom). The left column contains the observations, and the right column contains the models. The dashed ellipse indicates a semi-major axis of 130 au, which is the limit of applicability of our model. An orbital inclination of 51.7° was assumed, the same as for the continuum.
