Pal1-I (big empty red star) α-element abundance ratios are presented together with Sagittarius dSph stars (grey shaded area) from S07, and stars in the GCs Pal 12 (big open blue triangle) and Ter 7 (big blue asterisk) from Cohen (2004) and S07, respectively. Stars in the CMa overdensity region in the background of the OC NGC 2477 are plotted as big open circles (Sbordone et al. 2005). M-giants in the GASS from Chou et al. (2010) are plotted as open diamonds.
