Notes. Columns are as follow. Column 1; progressive index. Column 2; name defined as “FQS-MC” followed by the Galactic coordinates of the cloud centroid. Columns 3 and 4: Galactic longitude and latitude of the cloud centroid. Column 5: intensity-weighted semi-major axis. Column 6: intensity-weighted semi-minor axis. Column 7: position angle w.r.t. the cube x-axis. Column 8: mean velocity. Column 9: velocity dispersion. Column 10: 13CO (1–0) integrated intensity across the area of the cloud. Column 11: kinematic distance from the Sun. Column 12: equivalent spherical radius. Column 13: area. Column 14: total mass derived from 13CO column density. Column 15: total mass derived from 12CO (1–0) line intensity multiplied for the X(12CO) factor. Column 16: total mass derived from Herschel H2 column density. Column 17: average surface density. Column 18: virial parameter. Column 19: number of dendrogram leaves. Column 20: flag1; 0 indicates that the cloud is fully mapped in the Herschel H2 column density map, 1 indicates that the area of the cloud as derived from the 13CO (1–0) data is only partially covered or not covered at all by the Herschel H2 column density map; for those clouds Mdust and Σ are lower limits and αvir is an upper limit. Column 21: flag2; 0 means that the cloud is fully mapped in 13CO (1–0), 2 means that the area of the cloud as derived from 13CO (1–0) reaches the edge of the map; these clouds could extend outside the mapped area, therefore the measured parameters show an uncertainty that depends on how much CO emission was missed.
