Left panel: CO(1–0) integrated intensity map obtained in the disk of NGC 1614. The map is shown on color scale with contour levels 5%, 10%, 15%, 20%, to 90% in steps of 10% of the peak value =14 Jy km s-1beam-1 (~50σ). Middle panel: the CO(1–0) isovelocity contours spanning the range (−120 km s-1, 120 km s-1) in steps of 20 km s-1 are overlaid on a false-color velocity map (linear color scale as shown). Velocities refer to vsys(HEL) = 4763 km s-1. Right panel: overlay of the CO(1–0) line widths (FWHM) shown in contours (30, 45 to 195 km s-1 in steps of 30 km s-1) on a false-color width map (linear scale as shown). The filled ellipses in the bottom left corner of each panel represent the CO(10) beam size obtained with uniform weighting ( at PA = 23°). The position of the dynamical center is highlighted by the cross marker.
