\caption{Location and designation of the resonances in the photoionization spectrum of N$^{2+}$. The peak numbers refer to Figs. \ref{fig3} and~\ref{fig.niii}, and * denotes that the initial state of the transition is the 2s2p$^{2}$ $^{4}$P metastable states -- otherwise the initial state is the 2s$^{2}$2p $^{2}$P ground state. When several terms are given the MCDF and \citet{nist} energies correspond to the mean value of the terms energy weighted by their statistical population. The accuracy of the experimental energies listed is about 15 meV.\label{tab2}}
