Obtained by the CPL measurements at the 5D0→7F1 (magnetic dipole, λ = 590.6-592.8 nm) and 5D0→7F2 (electric dipole, λ = 613-614 nm) transitions; All the glum values reported in this study have been measured with a standard deviation, σd, of ±0.01 and ±0.001 for the CPL spectra of the 5D0→7F1 and 7F2 transitions, respectively.
