In total, 107 CO clouds have been identified, 55 of which were detected at more than 3 observed positions. For the 55 clouds, the physical properties, such as size, line-width, virial mass, and CO luminosity, are cataloged. File Summary:

Note (1): The CO clouds are named according to the positions of the intensity peaks in equatorial coordinates. Note (2): Positions of the observed points with the maximum 12CO integrated intensities within the CO clouds are given in equatorial coordinates.

Note (1): Line-widths, derived by using a single Gaussian fitting for a spectrum obtained by averaging all the spectra within a single cloud Note (2): Effective radii, defined as R=(A/π)0.5, where A is the total cloud surface area. Note (3): CO luminosity of the cloud. This is determined from the average integrated intensity of the cloud multiplied by the cloud area. Note (4): Virial masses of the CO clouds, a density profile of ρ∝r^-1 was assumed; the virial mass is written as Mvir/M=190[ΔVcomp_(km/s]2R(pc) (MacLaren et al., 1988ApJ...333..821M).
