Notes. See Salomé et al. (2008a) for complementary data. Tmb = main-beam temperature at line peak; V = velocity relative to systemic; ΔV = line width (FWHM); ICO = integrated line intensity; Mgas(H + He) is for 
= 4.6 M⊙ (K kms-1 pc2)-1 (Solomon et al. 1997). Note that the integration time is not the same for all regions, so the rms (computed for a spectral resolution of 42 km s-1) varies from one pointing to another.
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.
