The tuned functionals LRC-ω IE PBEh and LRCω GDD PBEh with c hfx = 0.2 afford very similar error distributions as compared to the corresponding functionals with c hfx = 0, as shown in Fig. . For non-LRC functionals, however, increasing the amount of exact exchange has a significant impact on mean signed error (MSE) for these localized excitations. TD-PBE calculations systematically underestimate excitation energies, which is typical of semilocal functionals, with a MSE of -0.45 eV for this data set. For TD-PBE0, the MSE is reduced to -0.13 eV and the mean absolute error (MAE) is 0.24 eV, which is as good as any standard functional for typical small-molecule benchmarks. MAEs for the tuned LRC functionals are similar but the MSEs are positive, consistent with a small upward shift in the excitation energies as compared to TD-PBE0. Finally, the HF-PBE functional,
