Sketch of the features identified in the CBD of V892 Tau from the residual maps shown in Fig. 6. The black line corresponds to the 3σ contour of the disc emission. The indicated high brightness residuals come from the moment 0 residuals. The spiral arms are identified on the velocity residual map, from which only the red part is plotted and the centre masked for clarity reasons. The temperature asymmetry coming from the peak temperature residual map is overlaid in dark brown. The arrow in the top left indicates the direction of V892 Tau NE.
