Table 1

Selected spectral lines and their atomic parameters.

Line λ0 (nm) χ1 (eV) log ɡf ɡeff log γrad
Fe I 624 624.2367 2.220 −3.233 1.0 6.880
Fe I 627 627.3004 3.329 −2.703 1.5 8.230
Fe I 680 680.6141 4.575 −1.813 1.15 7.850
Fe II 771 771.3845 3.903 −2.47 1.4 8.615

Notes. We list the vacuum wavelength (λ0), the excitation energy of the lower level (χ1) the logarithm of the oscillator strength times the multiplicity of the lower level (log ɡf), the effective Landé factor (ɡeff), and the radiative damping constant (γrad).

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.
