Appendix A: CO Spectra

Figure A.1 shows the CO(1–0) profiles of the detections and tentative detections observed by us at the IRAM 30 m telescope and Fig. A.2 those observed at the FCRAO 14 m telescope.

thumbnail Fig. A.1

CO(1–0) spectra for the galaxies detected with the IRAM 30 m telescope. The x-axis represents the recession velocity in  km s-1 and the y-axis the main beam brightness temperature Tmb in K. The spectral resolution is 20.8  km s-1 in most cases except for some individual galaxies for which a higher or lower resolution was required to clearly show the line. The full (red) line segment shows the line width of the CO line adopted for the determination of the velocity integrated intensity. The dashed (black) line segment is the HI line width at 20% peak level, W20. An asterisk next to the name indicates a marginal detection.

thumbnail Fig. A.2

CO(1–0) spectra of the galaxies detected with the FCRAO telescope. The spectral resolution is 13.1 or 26  km s-1, depending on the spectral shape and rms noise. The x-axis represents the recession velocity in  km s-1 and the y-axis the intensity in K in the Tmb scale. The full (red) line segment shows the line width of the CO line adopted for the determination of the velocity integrated intensity. The dashed (black) line segment is the HI line width at 20% peak level, W20. An asterisk next to the name indicates a marginal detection.
