Gas kinematics for the CO molecular lines. Centroid LoS Gaussian moment maps for the data (left columns), Keplerian model (center columns), and data-model residuals (right columns), for the ¹²CO (top) and ¹³CO (middle) data, using high-resolution cubes. The geometry of ¹²CO and ¹³CO models was fixed to the ¹³CO disk, which is less perturbed and has a higher S/N than C¹⁸O. For C¹⁸O (bottom), we employ the fiducial cube. The respective beam sizes are shown in the lower left corners. In ¹²CO-residuals, we overplotted the IR contours from Fig. 1a. All panels share the same scale, color bars, and are masked at 4σ of their peak intensity map. The innermost beam size is masked in as it was excluded from the fit.
