[N/Fe] versus [C/Fe] anticorrelation as obtained from the first abundance determination run. The red line divides MS targets on the right from RGB/HB/AGB targets on the left. SGB targets are located on both sides of the red line. The black line divides FG from SG stars. Red arrows indicate stars for which Marino et al. (2016) gives no [N/Fe]. For these stars we assumed [N/Fe]=0.0 as an upper limit (see text for more details).
