Notes.

^(a)

Negative values represent emission. Note some sources show lines in absorption. There are no measurements where the spectra show no indication of a line being present. NA indicates where the wavelength of the line was not covered in the observation.

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.
