The evaluation of the different terms in the density-based energy correction for db-MFCC and db-MFCC-MBE(2) has been implemented as described in Ref. . All these terms have been evaluated using the supermolecular numerical integration grid. In the evaluation of the Coulomb contributions, the corrections necessary for ADF's fitted density are included consistently . For evaluating the nonadditive exchange-correlation and kinetic energy functionals, the XCFun library was used, and the BP86 and PW91k functionals were applied.
