Notes. The FWHM, the line centres, and the velocity shift are found by fitting the profiles to a Gaussian. The error estimates are the three sigma errors from the fitting of the Gaussian. Large error bars, when present, are due to the HI profiles being poorly approximated by a Gaussian profile.

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.
