Finally, extrapolating from the TQ5 points with Martin4 and Peterson gives similar smallest deviations when the energies are CP-corrected, and the same applies to Helgaker and Peterson when using all DTQ5 points, but Helgaker is performing somewhat better for the augmented sets. Note that the extrapolations that include the (aug-)cc-pV5Z data point do not further improve the interaction energies (Table ), with an average MAE(max dev.) against PWs of 0.06(0.17) kcal/mol that is comparable to the 0.07(0.18) kcal/mol for the non-extrapolated results (Table ). This remaining difference is discussed below in Section IV E.
