141 /↓↓ ++/ // // Shallow, warm gas gap. Detected in 12CO and 13CO kinematics, and in 12CO line widths.
270 optical ↓↓/ /++ / / Vertical bumps and positive velocity gradients near the location of kinematic kink at R = 260 au (Pinte et al. 2018a; Izquierdo et al. 2022)

67 / Θ / // Pressure bumps detected in kinematics, leading to dust ring. Line broadening in 12CO indicative of higher density.
101 / /-- ↓↓ /↑↑ High line broadening in C18O hinting at enhanced turbulent motions. Pressure bumps detected in kinematics, leading to dust ring.
159 / Θ / / Pressure bumps detected in kinematics, leading to dust ring.

120 / / /+ ↑↑ ↓↓ Funnel-like structure causing radial offset between pressure bumps observed in 12CO compared to those in 13CO and C18O (see Sect. 4)
