A summary figure showing the coincidence of the CPD candidate with the ¹²CO/scattered-light gap and ¹²CO velocity kink. (a) Radial profiles of the normalized (black) ¹²CO integrated intensity and (red) the near-infrared scattered light (from Avenhaus et al. 2018; scaled by r ² to account for the drop in the incident stellar photons). The shaded region shows 1.″4–2.″0, the approximate radial location of the ¹²CO gap. (b) Radial profile of the normalized ¹³CO integrated intensity along the azimuthal location of the CPD (see Figure 3). (c) ¹²CO channel map at 4.8 km s⁻¹. The location of the ¹²CO gap is shown with the gray dashed ellipses. Black contours show the dust continuum from Andrews et al. (2018). (d) A zoom-in of the blue box in panel (c), showing the velocity kink in ¹²CO (background color map) within the ¹²CO gap (black dashed curves). The blue contours show ¹³CO emission at 10σ and 15σ levels. Note that the CPD candidate is located at the center of the ¹²CO gap and coincides with the velocity kink in ¹²CO, highly suggestive of the presence of an embedded planet. The synthesized beams for ¹²CO and ¹³CO data are shown in the lower-left and lower-right corners of the panel, respectively.
