Notes. The frequency, quantum numbers (QNs), the energy of the upper level (Eu), the logarithm of the Einstein coefficients (log Aul), the root mean square (rms) of the analysed spectral region, the integrated intensity (
), and the signal-to-noise ratio in integrated intensity (S/N) are given.
Integrated intensity derived from MADCUBA LTE fit, see Sect. 3 for details.
