Notes. Mega metal-poor (MMP) stars with [Fe/H] < −6.0, hyper metal-poor (HMP) stars with [Fe/H] < −5.0, ultra metal-poor (UMP) stars with [Fe/H] < −4.0, extremely metal-poor (EMP) stars with [Fe/H] < −3.0, and metal-poor (MP) stars with [Fe/H] < −1.5. The table lists the CEMP-no stars presently known for which either the carbon isotopic ratio or the Li has been measured in the literature. In boldface are the new measurements presented in this paper. Limits are at the 3σ CL.
