Notes. Columns: target name, molecular species, line frequency at rest frame, channel rms, synthesized beam size, inner and outer radius used to integrate the flux, integrated flux, and column density calculated in the hypothesis of optically thin lines. The range of column densities reflects the solutions found in the range of gas temperature between 20 and 100 K. Brackets denote fluxes above 2σ uncertainty but below 3σ. Upper limits on HDO, CH3OH, and H2 CS are measured on the same area as the H2CO and CS.

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.
