Notes. From left to right: atomic element and ionization state, wavelength, total angular momentum quantum number of the lower Jl and upper Ju levels, the oscillator strength log(gf) and its standard deviation determined in this work, the excitation potential of the lower level χe, Landé g-factor, and the coefficients for collisional broadening (α and σ). The abundances were extracted from Asplund et al. (2009). Lines marked with a star (*) are used as the main lines in the inversions, the others are considered as blends in SIR. Also, a0 is the Bohr radius. Landé g-factors were computed using LS coupling.
