E(level): From least-squares fit to adopted Eγ, assigning 1 keV uncertainty to Eγ data for which the authors failed to state an uncertainty.

J^π(level): From band assignments, except as noted.

E(γ): From (¹⁹F,4nγ), except as noted; uncertainty unstated by authors.

I(γ): From ε decay (43 s), except as noted.

M(γ): From unenumerated γ(θ) in (α,6nγ), assigning Δπ=(no) for intraband transitions.
