Description: This tag specifies the coupling parameter of the energies and forces between a fully interacting system and a reference system.


The tag SCALEE sets the coupling parameter and hence controls the Hamiltonian of the calculation. By default SCALEE=1 and the scaling of the energies and forces via the coupling constant is internally skipped in the code. To enable the scaling SCALEE1 has to be specified.
