methods, Fig. plots absolute the CEBEs versus experiment using the ∆SCF, STM, and GSTM methods in conjunction with the SCAN functional. (The corresponding data computed using B3LYP are shown in Fig. .) The ∆SCF results follow the experimental trend line quite well, with little systematic error. In contrast, the STM and GSTM methods exhibit a roughly constant shift with respect to experiment, with STM calculations overestimating the CEBEs and GSTM results underestimating them by a smaller amount.
