param:
       IMPLICIT DOUBLE PRECISION (A-H,O-Z)
       parameter(n=16*4)
       DOUBLE COMPLEX   xi
       parameter(xi=(0.d0,1.d0))
       parameter(pi=3.141592653589793d0)
       parameter(nomi=n/2,emin=-10,emax=10,eim=0.02,ne=1000)

n is number of Matsubara points to deal with
nomi is the number of Matsubara points taken for the continuation (can be taken n/2, or n/2-10
emin, emax is the minimum and maximum energy (omega) on real axis
eim is the artificial broadening (how far we are from the real axis)
ne  is  the number of points on real axis: (emax-emin)/ne = energy step on real axis.
