These criteria exclude any possibility of the calculated excitations being inaccurate due to unavailable symmetry or mislabeled symmetry. Additionally, for ease of development and use of DMRG, we have excluded consideration of the 51 doublet excitations in the QUESTDB dataset. However, the proposed scheme is straightforwardly generalizable to these cases by use of ROHF orbitals, and we have addressed these cases in previous work. After eliminating data according to these criteria, we are left with a set of 199 excitations for testing the present method.
