`EXCHANGE`,*factor*

For Kohn-Sham calculations,
compute exchange energy according to Hartree-Fock formalism and add
the contribution scaled by *factor* to the fock matrix and the
energy functional. Otherwise, the default is *factor=0*, i.e.,
the exchange is assumed to be contained in the functional, and only the
Coulomb interaction is calculated explicitly.

`DFTFACTOR`,*fac1, fac2, ...*

Provide a factor for each functional specified. The functionals will be combined accordingly. By default, all factors are one.
