Evaluation of the Dawson function and its antiderivative needed for the Gaussian broadening of piecewise polynomial functions
The broadening of a sharp (unbroadened) dielectric function is a fruitful parameterization of such effects. The unbroadened function is often taken as a piecewise model of a complex dielectric function...
