-   This function fits the Weiss field or Hybridization function (delta) with a discretized version. The fit parameters are the bath parameters contained in the user-accessible array. Depending on the type of system we are considering (normal, superconductive, non-SU(2)) a different set of inputs has to be passed.

Depending on the type of system we are considering (normal, superconductive, non-SU(2)) a different set of inputs has to be passed. The specifics of the numerical fitting routines are controlled in the input file.
