Na-Oanti-correlation plane (top), and the same for Na-Mg (bottom; Al measurements are not available). Reference data for GCs are plotted as grey points (Pancino et al. 2017), and solar abundances as orange lines. Each OC star is coloured based on its projected rotational velocity, and the size of the symbols reflects Teff (hence, mass). Typical (median) error bars are plotted as red crosses.
