SO2CONV

    Useful
    

SO2CONV will convolute the single particle XAS files (`xmu.dat', `chi.dat', `feffNNNN.dat', etc.) from FEFF with a many body spectral function, to include many body effects in the spectra. This includes an ab-initio calculation of the amplitude reduction factor S$_0^2$. SO2CONV uses Hedin-Lundqvist self energies, so it will probably work best with XAS files calculated using FEFF's HL self energies.
