However, such an approach has to be critically considered when no complete knowledge of the reaction model is available. To get reliable results in such cases one has to use all the available information from independent sources and, accordingly, fix or constrain variations of the parameters. In this paper we present a thorough R-matrix analysis of the N-15(p,gamma)O-16 reaction, which provides a path from the CN cycle to the CNO bi-cycle and CNO tri-cycle.
