integer :: finite_basis_corr

This determined whether finite basis set corrections to the energy and stress will be performed. Possible values are

• 0 - No correction performed
• 1 - Correction performed with user provided estimate of $\frac{dE_{tot}}{d \log(E_{cut})}$.
• 2 - Correction performed with automatic calculation of $\frac{dE_{tot}}{d \log(E_{cut})}$.

The vlaue of this parameter is defined by the string parameter file keyword FINITE/SMALL>_BASIS/SMALL>_CORR as follows:

• NONE - 0
• MANUAL - 1
• AUTO - 2

For backwards compatability, the string ``0'' is equivalent to ``NONE'', ``1'' to ``MANUAL'' and ``2'' to ``AUTO''.

If FINITE/SMALL>_BASIS/SMALL>_CORR=``MANUAL'', the user must supply a value for keyword BASIS/SMALL>_DE/SMALL>_DLOGE.

The default value of this parameter is 2 if one of the following conditions are met:

• task=GEOMETRYOPTIMIZATION, geom_method=BFGS, fixed_npw=FALSE and the cell is not fixed; or
• task=MOLECULARDYNAMICS, fixed_npw=FALSE and the cell is not fixed; or
• calculate_stress = TRUE.

Otherwise, the default value is 0.
