Notes. Column 1: GMF name; Col. 2: total cloud derived from the integrated 13CO emission from the GRS down to 1 K km s-1; Col. 3: dense gas mass derived from dust continuum with ATLASGAL 870 μm data; Col. 4: dense gas mass fraction; Col. 5: Galactocentric radius; Col. 6: angle measured from the Galactic center-Sun line to the filament’s position in the disk; Col. 7: mean height above the Galactic midplane. Values in parentheses are for filaments which intersect with the projected plane. Column 8: association with star formation region or spiral arm.

(a)

The dense gas mass from the two filaments within GMF 38.1-32.4 partly overlap. While the envelope mass estimated from spectroscopic 13CO data accounts for the different velocity components, in the overlap regions, the ATLASGAL continuum data sums contributions from both components.
