[X/Fe] vs. [Fe/H] for NGC 6723 compared with results from literature. Alpha-elements Mg, Si, Ca, and iron-peak element Ti are shown in the four panels of the figure. Gray dots depict the K giant bulge field stars from Gonzalez et al. (2011). A brown star stand for the metal-poor globular cluster Terzan 4 (Origlia & Rich 2004). Red crosses stand for a number of metal-intermediate and metal-rich clusters from recent literature: NGC 6522 (Barbuy et al. 2009), HP1 (Barbuy et al. 2006), NGC 6558 (Barbuy et al. 2007), NGC 6553 (Alves-Brito et al. 2006), NGC 6528 (Zoccali et al. 2004), Terzan 1 (Valenti et al. 2015), NGC 6441 (Gratton et al. 2007), NGC 6388 (Wallerstein et al. 2007), NGC 6624 and NGC 6569 (Valenti et al. 2011), UKS1 and NGC 6539 (Origlia et al. 2005), NGC 6440 (Origlia et al. 2008), and NGC 6342 (Origlia et al. 2005).
