Notes. (b)Mean pointing offset. (a)Number of lines used or averaged. (c)Parent scale length in km. The value with uncertainty (or lower limit) is the one obtained from the χ2 minimisation. (d)Production rates from nuclear or distributed source with given parent scale length. (e)This χ2 for HCN(3–2) includes an additional 10% calibration uncertainty. Without, χ2 is about two orders of magnitude larger but minimisation leads to the same Lp.

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.
