Notes. The asterisks in the penultimate column denote if no fiducial measurements could be made. (a) Values for the velocity width, velocity asymmetry, and angular width are given only in the case of clear detections. (b) Values for the peak flux and integrated flux are given only for non-blended lines or lines with a minor blend contribution. (c) Comments based on appearance of line in the spectrum for the 300 mas extraction aperture. For more details: see Table A.1. (d) Comments based on the morphology of the zero-moment map. For more details: see Table A.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.
