Notes. For the IRDCs we indicate whether or not they show embedded 24 or 70 μm point sources with y(es) or n(o) (or “” if there are no data available). In the last column the sources of the dust continuum data are presented.

(a)

Unbracketed values are preferred, bracketed values are alternative values.

(b)

Dust continuum data. Either from IRAM 30 m observations with Mambo (1.2 mm), the galactic plane survey ATLASGAL (870 μm; Schuller et al. 2009), or the SCUBA Legacy Catalog (850 μm; Di Francesco et al. 2008).

(c)

Very weak emission compared with the background located at the same position as 24 μm emission source.

(d)

For vlsr = (97.6)111.3 km s-1.

(e)

For vlsr = (52.8)100.2 km s-1.

(f)

For vlsr = 94.3(98.4) km s-1.

(g)

No embedded central point source found, a nearby extended source with emission inside the beam is detected.

(i)

For the near (far) kinematic solution.

(j)

Parallactic (kinematic) distance.

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.

Initial download of the metrics may take a while.
