Notes. Numbering in Col. 2 is the same as in the last column of Table 1. Cols. 3–5 list (beneath each other) the fitting parameters Vlsr (km s-1) and b (km s-1) and the corresponding 
values. In Cols. 6, 7, the radial velocity differences are given. Estimates of the kinetic temperature and the nonthermal velocity component are in Cols. 8 and 9, respectively. The numbers in parentheses are 1σ statistical errors. The signal-to-nose ratio per spectral channel at the maximum intensity peak of NH3/HC3N is indicated in the last column.
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.
