Notes. (a) C17O has a hyperfine structure with three lines at 112 358.7770, 112 358.9820, and 112 360.0070 MHz according to the CMDS database. Both the JPL and LAMDA databases (which our CASSIS analysis is based on) assume only one component at 112 359.284 MHz. In our observations, the lines at 112 358.7770 MHz and 112 358.9820 MHz are blended.
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.
