Notes. Columns 3–5 show the intensities (photons) of the strongest lines, relative to the resonance transition at 171 Å. The intensities were calculated at log Te [K] = 5.85, the temperature of peak ion abundance in ionization equilibrium, and at log Ne [cm-3] = 8. Column 3 shows the present values, while Cols. 4, 5 those with the previous R-matrix calculation (Storey et al. 2002, S02) and the combined R-matrix + DW data (O’Dwyer et al. 2012), S02+B12. Columns 6, 7 show the gf and A values calculated in this work. The last two columns show the wavelengths corresponding to the experimental and target energies. Values in parenthesis list the corresponding wavelength difference. TN is a new tentative identification. R indicates a revised wavelength and bl indicates that the line is 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.
