  The potential energy curves for molecular ions up to $N_2^{4+}$ are
calculated in an ab initio manner using the multi configurational
self-consistent field method. Specifically, we implement in an automatic way a
previously used double loop optimisation scheme within the multi
configurational self-consisted field method. We obtain the potential energy
curves up to $N_2^{4+}$ ions with any combination of core, inner valence, and
outer valence holes. Finally, we provide the code used to generate these
potential energy curves.
