[X/Fe] ratios plotted against [Fe/H] for the sample of six Boötes I stars (filled red circles) and the two comparison field halo stars (open blue circles). Black triangles represent the abundance results from the “GM” analysis in G13. Small gray circles present the abundances of field halo stars from Ishigaki et al. (2012, 2013). In the plot for [C/Fe]–[Fe/H], results from Norris et al. (2010a) for Boötes I stars are shown with crosses.
