Notes. (a) Correction factor to the molecular column density to account for the contribution of torsionally or vibrationally excited states to the partition function. All parameters are calculated for the given Tkin. (b) The molecular abundance (X) is calculated by X = N/N(H2). The values used for N(H2) are given in Table 2. (c)Velocity offset compared to the vlsr of − 43.5 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.
