E(level): For states connected by gammas, the excitation energies are from Eγ by using a least-squares adjustment procedure. The rest are from ⁵⁸Ni(p,t), except as noted.

J^π(level): From L transfer in ⁵⁸Ni(p,t), except as noted.

T_1/2(level): From ΔS(a) in ⁵⁴Fe(³He,n), (³He,nγ).

I(γ): Relative photon branching from each level renormalized to 100 for the strongest branching.
