E(level): From least-squares fit to Eγ values

Jπ(level): As proposed by 2016Jo01, based on γγ(θ)(DCO) data for the 450 and 563 transitions, and band structures for the remaining levels

E(γ): Weighted averages taken when values are available from 92Mo(78Kr,2αγ) and 106Cd(60Ni,2p2nγ), otherwise from from the (78Kr,2αγ) reaction
