The R-Matrix computer code AZURE is designed for the analysis of excitation curves containing complicated interference effects not only from resonances but also direct capture contributions.  The reaction ¹⁶O(a,g)²⁰Ne cross section from E_cm ~ 1 to 3.5 MeV is just such a case.  A brief overview of R-Matrix theory as it pertains to AZURE will be given followed by a short summery of the experiment.  The bulk of the talk will be spent demonstrating how one practically applies AZURE to this type of reaction.
