Notes. Integrated flux, velocity, and FWHM obtained through Gaussian fits. Velocities are counted from the central redshifts indicated in Table 1. The H2 masses are estimated within the CO(1–0) beam of 23″, with the standard conversion factor of the Milky Way α = 4.36 M (K km s−1 pc2)−1. Upper limits are given at 3σ, assuming an FWHM of 300 km s−1.

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.
