E(level): From least-squares fit to adopted Eγ, assigning 1 keV uncertainty to Eγ data for which authors did not state an uncertainty and omitting uncertainly-placed transitions, unless all transitions from a given level are of that character.

J^π(level): Values given without further justification are based on rotational band structure.

M(γ): From α(K)exp or intensity balance in β^- decay, except as noted.
