Notes. Numbers in parentheses indicate the standard deviation error, "high" and "low" mean the column densities derived by fixed excitation temperatures at 20 K and 6.5 K, respectively. Without these indications, we fixed the excitation temperatures at 20 K.
(a) The column densities are derived by the rotational diagram method.
(b) The 2nd velocity component.
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.
