Notes. Column 2: quantum numbers; Col. 6: integrated intensity (in antenna temperature) of the line with its formal uncertainty; Col. 7: expansion velocity derived from the linewidth with its uncertainty which includes the width of half a channel (1 MHz) except for the lines with a low S/N where a full channel (2 MHz) is included. The uncertainties given (within parentheses) do not include additional uncertainties derived from the absolute flux calibration. (HB) Hard blend, thus, we cannot estimate the contribution of the line to the spectral feature observed. (BF) Bad fit.

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.
