PHON_SIGMA

Default: PHON_SIGMA

= 0.0005 eV

Description: Set the width of the Gaussian function in eV to compute the phonon density of states.

The density of states is computed between $[\omega_{\text{min}}-5\sigma,\omega_{\text{max}}+5\sigma]$ with $\omega_{\text{min}}$ and $\omega_{\text{max}}$ the lowest and highest phonon frequency and $\sigma$ the broadening PHON_SIGMA. The number of energy points in this interval is set by PHON_NEDOS.
