For the cc-pVXZ sequence of basis sets, mean absolute errors (MAEs) for all PNO thresholds are consistent across the cardinality of the basis set: double-ζ, tripleζ, or quadruple-ζ. (Individual errors can be found in Fig. whereas Table presents a statistical summary.) The most aggressive or least conservative threshold is the "loose CCSD(T)" value (T CutPNO = 10 -6 ), for which the MAEs are 0.13, 0.15, and 0.16 kcal/mol for cc-pVDZ, cc-pVTZ, and cc-pVQZ, respectively, and the maximum DLPNO error is < 0.4 kcal/mol. Histogram of the errors can be found in Fig. , leading to a standard deviation of < 0.1 kcal/mol that is also consistent across cardinality. Similar trends are observed for Karlsruhe basis sets (Fig. ) and will not be discussed in detail.
