Position-velocity diagrams along the kinematic major and minor axis. Left panel: PV plot along PA = 248 deg (the kinematic major axis). Right panel: PV plot along PA = 338 deg (the kinematic minor axis). The slit width is set to 0.45 arcsec (approximately the FWHM size of the synthetic beam major axis). The white contours refer to data, and are drawn at (1, 2, 4, 8, 16, 32) × σ; the black dots give the V_LOS value from the ^3DBAROLO model.
