Position-velocity diagrams along the semi-major axis of the disk (PA = 118.8°) for CN-1 (top) and CN-2 (bottom, with two hyperfine group transitions). The offset is positive toward the east side of the disk and negative toward the west. The horizontal lines give the systemic velocity (~1.95 km s⁻¹), shifted for CN-2 hf2 emission to ~5.3 km s⁻¹. The blue curve shows the expected Keplerian velocity curve assuming a flat disk geometry. The dashed black line is the expected Keplerian velocity considering the derived best-fit model for the vertical profile of each tracer. Both models consider a stellar mass of 0.46 M_⊙, as derived in Veronesi et al. (2021). The east and west sides of the disk are indicated in the bottom panel for reference.
