Notes. The ID number shows the catalogue number associated with the cloud (same as the colour-scale in Fig. 9). The GMC name is defined as SDG (for SEDIGISM) followed by the Galactic coordinates of the clouds’ centroid. Columns 3 and 4 show the intensity-weighted semi-major and semi-minor axes, a and b, respectively; Column 5 shows the position angle (PA), and Col. 6 shows the aspect ratio (AR) defined as a/b. In Cols. 7–9 we show the centroid velocity, velocity dispersion, and average 13CO (2–1) integrated intensity across the area of the cloud. Column 10 shows the number of dendrogram leaves, Nl, that make up each GMC. Column 11 shows the adopted distances (d) and their uncertainties. Columns 12–14 show the exact area defined by the clouds’ masks, the equivalent radius (R, assuming circular geometry) and maximum length (lmax). Columns 15–17 show the total mass (M), the average surface density (Σ), and the virial parameter (αvir). See Sect. 4.4 for details.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
