  Methodology is presented for analysis of two-particle azimuthal angle
correlation functions obtained in collisions at ultra-relativistic energies. We
show that harmonic and di-jet contributions to these correlation functions can
be reliably decomposed by two techniques to give an accurate measurement of the
jet-pair distribution. Results from detailed Monte Carlo simulations are used
to demonstrate the efficacy of these techniques in the study of possible
modifications to jet topologies in heavy ion reactions.
