Notes. Column 1 gives the name of the selected clouds. Column 2 gives the median of excitation temperature (the detailed statistical results are described in Appendix B). Column 3 gives the intensity-weighted radius of the clouds. Column 4 gives the line width of the 13CO average spectrum. The areas, surface densities, cloud masses derived from 12CO and 13CO are listed in Cols. 5–10.
