Main characteristics of the models computed in this work, with the initial mass M_ini, [Fe/H] ratio, initial metallicity in mass fraction Z, initial chemical composition (solar-scaled or α-enhanced), total lifetime τ_star, duration of the AGB phase τ_AGB, final mass M_fin, and final mass of the convective envelope , number of pulses N_pulse, along with information on whether the model experiences a PIE or not and the pulse number during which the PIE arises.
