For both data sets, convergence with respect to T CutPNO is monotonic at the RI-MP2/cc-pVDZ level but erratic at the RI-MP2/jun-cc-pVDZ level, so the anomalies are clearly attributable to the diffuse basis functions. As such, DLPNO calculations with diffuse basis functions should not be used in T CutPNO → 0 extrapolations. On the other hand, when loose-MP2 thresholds are used, the DLPNO error for jun-cc-pVDZ is consistently (and in some cases, significantly) smaller than the error obtained using cc-pVDZ, for both the L7 and the S12L complexes. This is something of an artifact for loose thresholds, however. For normal-MP2 thresholds the errors are typically (though not always) smaller for cc-pVDZ than for jun-cc-pVDZ, and for tight-MP2 thresholds the error is always smaller for the non-augmented basis set.
