Reconstructed images of dust continuum emission and ¹²CO. From left to right: dust continuum emission from CS Cha imaged with a robust parameter of −0.5, moment 0 and moment 1 of the ¹²CO imaged with a robust of −0.2, and radial profiles for the continuum and ¹²CO emission calculated by deprojecting the images with the inclination and position angle of Model 2e (see Sect. 3.3). The ellipse in the left bottom corner of the panels represents the synthesized beam of the images, which is 30 * 46 mas for the dust continuum and 80 * 77 mas for the ¹²CO. The scale bar in the top right of the first panel represents 20 au at the distance of the source. The Gaussians in the right panel represent the average radial resolution of the profiles, and in the same panel, the colored region in the profiles represent the 1 σ dispersion at each radial location.
