[X/Fe] vs. [Fe/H] for the α-elements (Mg, Si, Ca, and Ti), and the Fe-peak elements (Cr, Mn, Co, and Ni): open diamonds represent the thin-disk data (González Hernández et al. 2010, 2013); red diamonds are our stars compatible to within 1 rms with the Fe abundance but not for all elements; blue squares are the candidates selected to become members of the Ursa Major MG. Inverted green triangles show incompatible stars. The reference star, HD 115043, known to be a member of the Ursa Major nucleus, is marked with an orange circle. Also, representative error bars are displayed in each graph.
