Notes. Except when otherwise stated, the signature corresponds to the line NC. The field “N” indicates the number of lines used in the GLSP estimation, after removing low S/N and anomalous lines. NSP stands for “no significant period”. Energy includes excitation potential (Ek) and (for ions) ionisation potential (Ei), which are shown separately as a sum for clarity. Transition probabilities and line excitation potentials are not available for some of the lines. All atomic data are from the NIST database.
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.
