- | The double precision parameter pole_zero defines the smallness of the denominator in the relativistic h-term for the consideration of A as an actual resonance of the relativistic integration. An appropriate value is about 1.d-10. If |A + om*gamma*ms/kpar + nn*qs/kpar| is less than pole_zero, A is not considered a pole since it cancels with the denominator of the h-term. | + | The double precision parameter pole_zero defines the smallness of the numerator in the relativistic h-term for the consideration of A as an actual resonance of the relativistic integration.
