Notes. Sets (a), (b), and (c) refer to the Z = 0.02 stellar models with MZAMS = 15 M⊙, 20 M⊙, and 25 M⊙, respectively. The overshooting parameter value used in the stellar evolution code is reported in the first column for each set of stellar models with a fixed initial mass. The values of nc obtained by Käppeler et al. (1994) and The et al. (2007) for their Z = 0.02 stellar models with a similar mass and input physics are also reported for comparison (see columns labeled as K94 and T07, respectively). The sign “....” means datum not available.
