¹²CO (2–1) moment maps of V892 Tau. The integrated intensity, the peak temperature, the peak velocity, and the line width correspond to the first, second, third, and last rows, respectively. The first column shows moment maps computed from the data emission channels, the second column from the model and the last column shows the residuals in the detected disc area computed from the two previous maps. A mask defined by the 3σ contour of the data has been applied to the model before comparison with the data.
