Notes. Columns indicate the corresponding isotope (Col. 1), the branching isotopes (Col. 2) that affect its abundance, their decay modes, daughter nuclei, and decay rates (Col. 3-8). λSet 0 indicates the decay rate used in the Set 0 models from JINA reaclib, while and
indicate the value of the T-dependent rate at 90 and 300 million K, respectively. The decay rate values are given for two different electron number densities, if available in the NETGEN database. The direction in which the abundance of each isotope has changed in the Set 1 models compared to the Set 0 models and the relevance of each case are shown in Cols. 9 and 10, respectively.
