-alligned paragraph text+//Gout = ResponseFunction.ReducePoles(Gin, NPoles)// or //Gout = ResponseFunction.ReducePoles(Gin, NPolesVal, NPolesCon)// reduces the number of poles in $G_{in}$ to $N_{Poles}$ or to $N_{Poles}^{Val} + N_{Poles}^{Con}$ by merging poles close to each other with small spectral weight (residue) (see appendix of [[https://doi.org/10.1103/PhysRevB.90.085102||Phys. Rev. B 90, 085102]] for additional information). The algorithm with $N_{Poles}^{Val}$ and $N_{Poles}^{Con}$ set does not shift spectral weight between the conduction and valence states (set by the chemical potential).
