Notes.

(a)

Total number of YSOs per field.

(b)

The various line characteristics are derived via a Gaussian fit to the line. Values are provided if the peak is detected at 3-σ.

(c)

The rms is estimated using the go noise function in CLASS.

(d)

We use a systemic velocity vsys = 262.2 km s−1 for the LMC.

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.
