Notes. Each of the seven spectral ranges has its own scale of arbitrary units for the emission intensity, I, which are given logarithmically. The uncertainties of the other measurements are 0.001 cm-1 (ACE) and 0.008–0.015 cm-1 (NSO).

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.
