ALPS: The Arbitrary Linear Plasma


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. An appropriate value is about 1.d-7. 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 numerator of the h-term.

pole_zero has to be defined as a global variable for all relativistic runs.

pole_zero is part of the namelist &system.
