I want to calculate the G0W0 spectral function with shift \omega-\delta where $\delta=E^{GW}-E_{LDA}$. In the G0W0 out put _EIG file, I already have the unshift spectral function A(\omega) , imaginary and real parts of the self-energy. Now what I would like to calculate is A(\omega)= \Im \Sigma (\om...
