NGC 2683 Hi D array and model position velocity diagrams. The contour levels are (− 2,2,3,6,12,24,48,96) × 0.7 mJy/beam. The resolution is 61′′ × 51′′. The model includes an elliptical component with axis ratios of 1.43:1/1.25:1 and angles between the bar’s major axis and the plane of the sky of 20° and 30°, a warp in inclination (I1), a centrally increasing velocity dispersion (VD), and a disk flare (F3).
