Notes.

(a)

Calculated as the FWHM of the elliptical Gaussian fitted to the line emission in the uv-plane (see Sect. 3.3.1). The line luminosity is L′ = πR2I, where R is the source size in column four in parsec (1′′ = 761 pc), and I is the integrated intensity (shown in Table 1) in units of K km s−1.

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.
