Notes. 

(a)

Different weighting schemes were used for continuum and line images. Major and minor axes and position angle (from north to east) are given.

(b)

rms noise is given for a frequency width of 1 km s-1 in the line maps. It is evaluated from  − 10 to  − 5′′ in both RA and Dec relative to the phase center.

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.
