Notes. The uncertainties on all velocity measurements are ±0.05 km s-1. Column 1: spectrum position number (as displayed in Figs. 2 and 3); Cols. 2 and 3: position coordinates; Col. 4: spectrum best-fit velocity; Col. 5: spectrum best-fit line width; Col. 6: spectrum non-thermal velocity dispersion component; Col. 7: spectrum total (thermal+non-thermal) velocity dispersion. We assumed a gas temperature of 12 K for these calculations.
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.
