After scaling of energies, significant improvements of the MAE and MAXE are only obtained for the sTDA and sTD-DFT approaches in combination with the large basis-set, (see Figure for e.g. BLYP). All functionals with scaled error value are listed in Table and a graphical illustration can be seen in Figure . Nonetheless, the MAE is still above 0.05 eV and high MAXE is obtained as well. Thus, GGAs and meta-GGAs cannot be recommended for calculations of UV-Vis-spectra of porphyrinoids.
