CUTOFF_SIGMA

CUTOFF_SIGMA = [real] ( [real] ) 

Default: CUTOFF_SIGMA

= 0.1

Description: CUTOFF_SIGMA specifies the broadening $\sigma$ 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 $\sigma$ 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.
