density fitting for the Coulomb problem. Density fitting basis sets are specified
as part of the model chemistry within the job's route section, discussed here.
DenFit is a synonym for this keyword.
Controls whether a generalized inverse is formed or the fitting equations are
solved iteratively. NonIterative is the default except for ADMP.
Set the tolerance for a non-trivial eigenvalue of the generalized inverse of the
fitting matrix to 10-N.
10-N as the convergence criterion for iterative solution of the fitting
equations. Implies Iterative. The default is 10-6 for ADMP
and 10–9 for the BOMD.
