Notes.

^(a)

Date of observations. If both subcompact and extended data are available, they are concatenated.

^(b)

1σ rms noise of the 1.3 mm continuum and the C¹⁸O 2–1 moment-zero maps. The units are mJy beam^-1 and mJy beam^-1 km s^-1, respectively.

^(c)

Synthesised beam sizes. The beam’s position angle is measured relative to the major axis from North through East.

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.
