epsilon

usage: epsilon [-h] [--omegaMin OMEGAMIN] [--omegaMax OMEGAMAX]
               [--n_omega N_OMEGA] [--gamma GAMMA] [--prefix PREFIX]

Compute dielectric tensor (epsilon) from DFT outputs. Each of the 9 tensor
components is written in a dat file, where first, second and third columns are
the frequency [eV], real(epsilon) and imag(epsilon) respectively.

options:
  -h, --help           show this help message and exit
  --omegaMin OMEGAMIN  Starting frequency of the energy grid [eV]. Default=0.0
  --omegaMax OMEGAMAX  Frequency cutoff for the energy grid [eV]. Default=0.0
  --n_omega N_OMEGA    Size of the energy grid. Default=1
  --gamma GAMMA        Gaussian broadening parameter [eV]. Defualt=0.2
  --prefix PREFIX      Prefix of DFT outputs. Default=totalE
