Notes. (1)A(B) = A×10B. (a)The fractional abundance relative to H2 is from Agúndez et al. (2019), and the spatial resolution is ~5000 AU. (b)The fractional abundance relative to H2 is from Oya et al. (2017), and the spatial resolution is ~100 AU. (c) The fractional abundance relative to CH3OH is from Jacobsen et al. (2019), and the spatial resolution is ~20 AU. (2)The simulated beam-average fractional abundances have already been smoothed to their respective spatial resolutions. Boldface indicates a disagreement of more than one order of magnitude between the observed and modeled value.

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.
