Notes. Strongest transitions are listed together with the wavelengths of their selfblends. Intensities relative to the strongest line are listed for the Maxwellian distribution, κ = 5 and 2, for log(T [K]) = 6.6 and log(Ne [cm−3]) = 9. Possible blending transitions in the vicinity are indicated by “bl”. “u” indicates and unidentified transition. “th” denotes that the wavelength is theoretical only. “w” denotes a weak line, while “s” indicates that the line can be stronger than the corresponding Fe XVII one.
