CUTOFF_SIGMA

CUTOFF_SIGMA = [real] ( [real] )

Default: CUTOFF_SIGMA

= 0.1

Description: CUTOFF_SIGMA specifies the broadening [math]\displaystyle{ \sigma }[/math] in eV for the cutoff function specified by CUTOFF_TYPE.

Corresponds to a broadening of the cutoff function used in the one-shot method to obtain Wannier functions. The meaning of [math]\displaystyle{ \sigma }[/math] depends on the CUTOFF_TYPE tag.

For spin-polarized calculations (ISPIN = 2), two values can be specified for CUTOFF_SIGMA, one for each spin channel. If only a single value is specified, it will be used for both spin channels.
