epsilon

usage: epsilon [-h] [--omegaMin OMEGAMIN] [--omegaMax OMEGAMAX]
               [--n_omega N_OMEGA] [--gamma GAMMA] [--E_threshold E_THRESHOLD]
               [--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.
