We next examine extrapolation of the DLPNO results to the canonical limit T CutPNO → 0, using the L/N and N/T procedures described in Section II D. Table summarizes DLPNO errors in various basis sets, for extrapolations that use either the CCSD(T) or the MP2 values of T CutDO and T CutPNO . (Regardless of thresholds, aAll of the calculations summarized in Table are RI-MP2 calculations.) Individual data for the entire S66 set can be found in Section S1 of the Supplementary Material.
