Notes. (a) At a distance of 3.33 kpc, 0″. 07 is equivalent to a projected spatial scale of 230 au. (b) Classification of the spatial distribution (I: single-peaked, II: double-peaked, III: ring-like) and position of the peak integrated intensity: P for the position of the 1.37 mm continuum peak at α(J2000) = 20:29:24.88 and δ(J2000) = +40:11:19.47; cardinal directions (e.g., N, NE) for orientation with respect to the position of the 1.37 mm continuum peak.

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.
