Notes.

(a)

Beam-deconvolved size estimated in the UV-plane by using the UVMODELFIT task.

(b)

Under the assumption that the continuum emission at 3 mm is completely associated to thermal dust continuum emission. We assume a Td = 40–60 K and a β = 2.0.

(c)

For 2QZJ0028 and HB8903, we assume a line width of 400 km s-1 and the upper limits correspond to a 3σ level.

(d)

Assuming a r31 = 1.0 ± 0.5. The statistical errors associated to the molecular gas include r31 uncertainties.

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.
