Spatial distribution of the EMPS analyzed in this paper. The grey circles show the Sculptor member stars from the CaT analysis from Battaglia et al. (2008a). The orange circles indicate our new sample of stars with chemical abundances derived from high-resolution spectroscopy. The star symbols identify the EMPS of Frebel et al. (2010a) and Simon et al. (2015), while the upright triangles points to the sample of Tafelmeyer et al. (2010) and inverted triangles the EMPS of Starkenburg et al. (2013), which have not been reanalyzed at high resolution.
