Caption: Figure 3.

(Red) Radial profile of the ¹³CO integrated intensity along the location of the point source, averaged over ±2° in position angle around the point source. (Black) Azimuthally averaged radial profile of the ¹³CO integrated intensity excluding the point source. The gray and red shaded regions show the standard deviation of the integrated intensity in each 0.″05 radial bin. The point source is seen well above the azimuthally averaged integrated intensity. The gap at ≃0.″5–0.″6 is consistent with the ¹³CO gap previously reported by Law et al. (2021a). The size of the major axis of the synthesized beam is shown with the black horizontal bar.
