Notes. G, v0 and θ are the gradient amplitude, mean velocity on the source continuum peak position, and gradient position angle (from the north to the east), respectively. Δθ is the difference between θ and the direction perpendicular to the jet. Missing values correspond to lines with insufficient signal-to-noise ratio to fit a gradient. L1521F and SerpM-SMM4 are not included in this Table, because no velocity gradient could be fitted for any of the observed lines.
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.
