Azimuthally averaged brightness temperature profile calculated from the CLEAN image of the dust continuum shown as dashed red lines. The brightness temperature profile for the ¹²CO is shown as a dotted blue line, as measured from the peak brightness LB image. The inner three beams have been excluded due to the brightness dilution in the channel maps. The colored regions show the 1σ dispersion at each location. The Gaussians in the right part of each panel represent the average radial resolution of the dust continuum image and LB ¹²CO. The beam sizes are shown in Fig. 1 and 7.
