¹²CO J = 3−2 and ¹³CO J = 3−2 channel maps. Each row shows the CLEAN image of the observation, the best visibility model, and the image made from the residual visibilities. The scale bar in the upper left panels is 10 au in size, while the beam size is shown in the lower left corner of the first panels. The number in the upper left corner shows the channel velocity relative to the resting frequency of each line, in m s⁻¹.
