Position-velocity diagrams along the major (top panels) and minor (bottom panels) axis of the of the CO(3–2) emission (left) and the R₃₂ line ratios (right) for J1010. The PVDs were extracted in a slit of 0$\stackrel{″}{.}$6 width along the major (PA = 288°) and minor (PA = 198°) axis of the CO disk and are displayed above 2σ_rms. The contours are 2, 4, 8, and 16σ_rms, with σ_rms = 0.3 mJy beam⁻¹ for CO(3–2) in the left panels. The red contours shown in the left and middle panels correspond to the corresponding ^3DBAROLO model at 2, 4, and 6σ_rms, and the grey dots are the derived rotation velocities. Right panels are the PVDs of the CO(3–2)/CO(2–1) line ratios. The color bars correspond to flux density in mJy for the CO(3–2) PVDs and brightness temperature ratio R₃₂, which is dimensionless.
