Note: the relative intensities (photons) ${\rm Int}=N_{j} A_{ji}/N_{\rm e}$ are normalised to the strongest transition and were calculated at an electron density of 109 cm-3and a temperature of $2.5\times 10^{5}$ K. Weighted oscillator strengths gf and A-values (s-1) are from the benchmark calculation. The gf values from WB08 are also listed (gf*). $\lambda_{\rm exp}$ are our experimental wavelengths, while $\lambda_{\rm th}$ are the theoretical ones from the benchmark calculation. $\lambda_{\rm NIST}$ are the NIST wavelengths. The last column (ID) provides a key to previous identifications. N indicates a new one proposed here. T N a tentative new one. FC73: Fawcett & Cowan (1973); E81: Ekberg (1981).
