+The relationship between the threshold and ground -- or more generally, extremal -- state energies is richer than
 in the real case. In Fig.~\ref{fig:eggs} these are shown in the
 complex-$\epsilon$ plane for several examples. Depending on the parameters, the
 threshold line always come at smaller magnitude than the ground state, or always
