Position-position-velocity plot illustrating the kinematics of the ¹³CO (1-0) and C¹⁸O (1-0) lines. Each data point represents the spatial location and centroid velocity of a Gaussian component, with colors distinguishing different Gaussian fits. The centroid velocity of the C¹⁸O (1-0) line is shown in orange, while the purple and red points correspond to the brighter and fainter intensity components of the ¹³CO (1-0) line, respectively.
