E(level): From least-squares fit to γ energies.

Jπ(level): Unless noted otherwise from (HI,xnγ) (1989Pa01) (see (HI,xnγ) for details)

M(γ): Unless noted otherwise, from (HI,xnγ) based on 1989Pa01 measured DCO values (intensity asymmetries) compared with typical values for stretched-Q and stretched-D transitions given in cited ref. See (HI,xnγ) for details
