Left column: velocity map of component I (Fig. 8) relative to VLA4A (top, V_VLA4A = 7.36 km s⁻¹) and VLA4B (bottom, V_VLA4B = 9.33 km s⁻¹). Middle: Keplerian disk model using the M_star and θ_inc from Diaz-Rodriguez et al. (2022). We note that the inclination angle of VLA4B is from the dust continuum as the gas disk is not seen here. Right: Toomre Q map derived using the physical parameters from CH₃CN plus models of rotation from the middle panel.
