Images of CIDA 1 ¹²CO channel maps are shown in the top, and ¹³CO channel maps are shown in the bottom. Each square is 3.0″ in width andheight, centered at the samed ¹³CO channel maps are shown in the bottom position as the dust continuum image. The contour level traces the 5σ emissionin the continuum image. The scale bar in the lower left panel is 20 au in size, and the beam size is found in the lower left corner of the same panel. Central velocities in km s⁻¹ of each channel are given in the upper left corner of each panel.
