Notes. Column: (1) Core ID; (2) Fiber ID; (3) & (4) central position in radio offsets respect to the map center, (Δα,Δδ); (5) peak intensity, Ipeak Intensity contrast respect to the surroundings, Ipeak/I0 ≥ 30%; (7) equivalent ; (8) Mass within FWHM, M; (9) central velocity, Vlsr; (10) non-thermal velocity dispersion, σNT/cs; (11) core ID in Rosolowsky et al. (2008) catalog; (12) gas kinetic temperature, TK (when available). Cores are ordered by increasing Δα.

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.
