PV diagrams of aGg’-(CH₂OH)₂, CH₃CHO, and CH₃OCHO from high-angular-resolution ALMA data (Diaz-Rodriguez et al. 2022). The dashed colored ellipses represent each kinematic component from the best-fit model (with the same colors as Fig. 6). The blue and red crosses indicate the positions and velocities of VLA4A and VLA4B, respectively. The white bar in the lower-left corner shows the beam size along the PV cut. NOEMA fits on top of the higher-resolution ALMA data match the structure, validating the NOEMA fit results.
