Notes. For transitions involving 4d⁹5s², here abbreviated as 4d⁻¹, the values are from MCDHF/RCI. The uncertainties in column three in terms of the NIST ASD accuracy classes are based the relative differences between the FSMRCC and MCDHF/RCI values and the uncertainties in column four are based on the QQE approach. The final uncertainties, column five, are the worst of column 3 and 4. For transitions involving 4d⁹5s² the QQE approach is used for the uncertainty estimation.
