[C/N] ratios as functions of effective temperature for the most metal-rich GCs of our sample. RHB/eAGB stars are shown in magenta, while RGB stars are shown in green. The data are compared with a Lagarde et al. (2012) 0.85 MZ = 0.0001 model (solid black line). This model has been shifted by −0.5 in C/N to match approximately the post-first dredge up C/N data value.
