Table 2: Fe⁺²² level energies in rydberg units relative to the ground state. Theoretical results from the Breit-Pauli R-matrix program. Observed results from Corliss & Sugar (1982) assuming 1 Ry = 109737.32 $\rm cm^{-1}$ . % diff is the percentage difference between the theoretical and observed energies.
