All results were obtained with the def2-QZVP basis set.
For each data point of the subset, the actual result in Eh and the 
deviation from the reference value ("Res. - Ref."; in kcal/mol) are given.
At the end of the table, mean (MD), mean absolute (MAD), root mean square (RMSD),
 maximum (max) and minimum (min) deviations are shown.
The results were published in: Goerigk, L.; Grimme, S.  J. Chem. Theory Comput. 2010, 6, 107-126.
