E(level): From least-squares fit to adopted Eγ, except where noted or where cross references clearly indicate other source. 1 keV uncertainty has been assumed in Eγ for which authors did not state an uncertainty.

J^π(level): From intensity patterns for rotational states, absolute cross sections, and σ(θ) in ¹⁷⁰Er(d,p), except where noted.

I(γ): Relative photon branching from each level; values are from ¹⁷¹Ho β^- decay, except where noted. Upper limits are given for photon branchings affected by multiple placement.
