Notes.

^(a)

All dust clumps are located at a distance of 2.42 kpc except D2 which is located at 5.4 kpc.

^(b)

These values are based on the catalog of Rosolowsky et al. (2010).

^(c)

The velocity information is based on the corresponding ¹³CO spectra.

^(d)

The corresponding beamsize is 40′′.

^(e)

The CO excitation temperature is extracted toward the position of each dust clump.
