Notes. Only the mass range of the stars that become carbon stars is considered. The various columns report the following quantities: 1 – initial mass; 2 – formation epoch; 3 – duration of the TP-AGB phase; 4 – fraction of the AGB phase spent as carbon star; 5 – luminosity range of the interpulse phases; 6 – final surface C/O; 7/8/9 – largest DPR (7), optical depth (8) and λ (9).
