Notes.
Reference models as obtained by assuming solar composition (Lodders et al. 2009), O+p reaction rates from Iliadis et al. (2010) and solar-calibrated mixing length.
Models obtained using the lower and upper proton capture rates of 17O or 18O suggested by Iliadis et al. (2010). All other parameters equal to reference models. Model BL: capture rates setting chosen to minimize 18O depletion.
