Helium mass fraction Y versus νesini (upper panel) and log gc (lower panel). Symbols and colors have the same meaning as in Fig. 5. Gray diamonds denote stars with LC III to I from Mokiem et al. (2007a). The purple dashed line at Y = 0.255 defines the initial composition for LMC stars; the gray bar is the 3σ uncertainty in this number.
