^aIn kcal/mol.

^bIn %.

^cWith TPSS-GL2.

^dCorrected for size-consistency error (see ref (61)).

^eThe best result between ISI and mISI of each line is highlighted in bold style. The OEP2-sc results are fully self-consistent, the MP2 and (reference) CCSD(T) results are calculated on top of HF orbitals, and the results of the other methods (GL2, ISI, mISI, mISI@TPSS-GL2, ACSC) are computed on top of OEPx orbitals.
