Notes. The errors show the uncertainties in the measured integrated fluxes and determined optical depths. Column densities written as a(x) = a × 10x. H2 column density is averaged over a 29″-beam and for all other molecules over a 30″-beam. The given errors are uncertainties in the measured integrated fluxes and the optical depth τ. The high uncertainties are in some cases due to high uncertainties in the determined optical depth.
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.
