Notes. (a) Negative VHM values correspond to the blueshifted side of the line (due to a sun-ward jet). (b) Ordered by ~ increasing lifetime. (c)Data obtained mostly with the 10.4 m Caltech Submillimeter Observatory or Plateau Bure 15 m antennas and a 24 ± 4′′ beamsize. April–May data were obtained with the IRAM 30 m and a 12 ± 3′′ beamsize. (d)CS, HNC, and more notably SO and H2CO (which have a much shorter daughter/parent scale length ratio) are daughter molecules. Their scale length can be much longer than expected for a parent molecule.
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.
