Notes. For comparative purposes, we also added some selected non-rotating models or altered stellar winds. Mini corresponds to the initial mass. TP-AGB describes the main input physics during this evolutionary stage. VW refers to mass-loss rates by Vassiliadis & Wood (1993), SCN to the implementation of the search for convective neutrality approach to the determination of convective boundaries (see main text for details), and Schw to the implementation of the strict Schwarzschild criterion. f corresponds to the rotation parameter (f = 0 means there is no rotation). Mc, CHEB and Mc, SDU are, respectively, the H-exhausted core masses at the end of core He burning, and at the deepest advance of the second dredge-up. Mc, f and Menv, f are the final core mass and the H-rich envelope mass left at the end of our calculations. NTP, τTP-(S)AGB and ΔtIP are, respectively, the number of thermal pulses, the duration of the TP-(S)AGB (given from the first thermal pulse until the end of our computations), and the maximum interpulse period in each sequence. TBCE, Lmax and λ are, respectively, the maximum temperature at the base of the convective envelope, the maximum luminosity during the TP-(S)AGB, and the maximum TDU efficiency parameter. C/O is the ratio of final surface number abundances of carbon to oxygen.
