Notes. Shown are the upper and lower configurations, experimental wavelength (nm in air), and oscillator strengths obtained from various calculations. The log (gf) values in the penultimate column for the 777-triplet lines given by Magg et al. (2022) are based on the results calculated with both the GRASP and AUTOSTRUCTURE code. The values in the last column reported by Bautista et al. (2022) are obtained by averaging over results from multiple methods (MCDHF, R-matrix, pseudo-relativistic Hartree-Fock method+core-polarization effects, and CI).The log (gf) results from the present calculation are adjusted using experimental wavelengths.
