Notes. Sampled radii (R), observed rotation velocities (vobs), and relative errors (ev, obs) from CO and HI datacubes. Contributions to the circular velocity from the molecular gas disk (vH2), atomic gas disk (vHI), stellar disk (vd), and -if present- stellar bulge (vb), together with the corresponding surface densities at R. For convenience, the velocity contributions and surface density profiles of the stellar disk and the bulge are normalized to a mass-to-light ratio of 1 at 3.6 μm.
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.
