Combined PdBI+30 m CO(2−1) data toward NGC 3627 north and south (top and bottom panels, respectively). The colors show in the left and right panels the first (intensity-weighted peak velocities) and second moments (intensity-weighted line widths), respectively. The contours present the integrated intensities in the velocity regimes indicated above each panel from 5 to 95% of the peak intensities (in 10% steps). The stars in the right panels show the positions for spectrum extraction. Example spectra are shown in Fig. 3, and fit results are presented in Tables A.1 and A.2.
