Distribution of [Ni/Fe] (top) and [Cr/Fe] (bottom) for our sample of RGB stars in the Fornax dSph as blue filled circles. The cyan filled circles are the data of Letarte et al. (2010) and the cyan triangle the metal-poor star of Tafelmeyer et al. (2010). We also show in orange filled circles the stars in Fornax globular clusters from Letarte et al. (2006). MW halo stars from Venn et al. (2004) and Frebel (2010) and references therein are in small grey dots. Representative error bars are given for the metal-poor ([Fe/H] < –1.4 dex) and metal-rich ([Fe/H] > –1.4 dex) regimes.
