Notes. (a) Entry number in our Weeds local database; see Sect. 3.4.1. (b) Number of detected lines. One line of a given species may mean a group of transitions of this species that are blended together. (c) Source diameter (FWHM). (d) Rotational temperature used for the Weeds model. (e) Column density used for the Weeds model. X(Y) means X×10Y. (f) Rotational temperature derived from the population diagram. (g) Column density derived from the population diagram. In cases where molecules have two velocity components, the value represents the total column density summed over both components. (h) Correction factor that was applied to the column density to account for the contribution of vibrationally or torsionally excited states, in the cases where this contribution was not included in the partition function of the spectroscopic predictions. In most cases, this factor was estimated in the harmonic approximation (Eq. (1) in Belloche et al. 2025). (i) Correction factor that was applied to the column density to account for the contribution of conformers, in the cases where this contribution was not included in the partition function of the spectroscopic predictions. (j) Velocity offset with respect to the systemic velocity of MM1 (−71.7 km s)−1). (k) Linewidth (FWHM). (l) Tentative detection.
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.
