Fig. A.1


CO(10) spectra of the detected spectra (including tentative detections). The velocity resolution is ~20 km s-1 for most spectra and ~40 km s-1 for some cases where a lower resolution was required to clearly see the line. The red line segment shows the zero-level linewidth of the CO line adopted for the determination of the velocity integrated intensity. The blue upright arrow indicated the optical heliocentric recession velocity. An asterisk next to the name indicates a tentative detection.
