Notes. Molecular data adopted from the Leiden Atomic and Molecular Database (LAMDA, Schöier et al. 2005). Δυ is the original spectral resolution of our data, before they were smoothed to a common size of 1.0 km s−1. The CO 11−10 and CO 16−15 have two Δυ each, which correspond to observations in 2014 and 2016, respectively.
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.
