Notes. For CCS, H2S, CCCS, and SO2, only the transitions with Eu < 100 K are listed. (a)All parameters are taken from the CDMS catalogue (Endres et al. 2016), except that for SO+, for which we use the Jet Propulsory Laboratory (JPL) catalogue (Pickett et al. 1998). (b)Reference paper where the observations are presented. (c)Beam size. (d)We list only the two strongest hyperfine components.
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.
