Fornax displays a different chemical enrichment pattern from the MW. This is seen in the alpha-element evolution of the field stars and the GCs, which show a coupled chemical enrichment. Blue contours show the pattern of MW field stars from Venn et al. (2004) and Roederer et al. (2014). Fornax field stars come from Letarte et al. (2010; open gray), Lemasle et al. (2014; filled gray), and this work (filled gray with black edge). Star symbols show the location of the metal-deficient GCs H1, H2, H3 (filled, small red stars; Letarte et al. 2006), H3, H4, H5 (open red stars; Larsen et al. 2012) and the measurement for H4 presented in this work (filled large red star).
