Here you find various information on the brightest lines, ordered in wavelength:
Wavelengths (Angstroms); weighted oscillator strengths (gf);
transition probabilities (A);
intensities (normalised) at
106 , 1010, 1015, 1020
cm-3;
together with:
Configuration; Term; Index of the level (1=ground); Energy (observed if available - otherwise theoretical);
of the lower (l) and upper levels (u)
Note that intensities have been calculated at log T[K]=5.15, where the ion fraction peaks in ionization equilibrium. Only lines brighter than 0.001 the strongest line (at all densities) are retained.
Lines flagged with a "*" before their wavelengths only have theoretical energy levels.
Please note that their wavelengths are not very accurate.
