[Mn/Fe], [Cu/Fe] and [Zn/Fe] vs. [Fe/H]. Error bars represent the highest values for the uncertainties for each axis. Symbols: triangles are results from this work, where filled triangles are barium stars and open triangles, those stars considered to be normal by Smiljanic et al. (2007); filled squares are data taken from Allen & Barbuy (2006a); filled pentagon: Pereira & Junqueira (2003); crosses: Junqueira & Pereira (2001); open square: BD-21° 3873, a halo symbiotic star of Pereira & Porto de Mello (1997); starred triangle: HE2-467, a halo yellow symbiotic star of Pereira et al. (1998); starred squares: Castro et al. (1999); open pentagons: Luck & Bond (1991); open circles: Smith et al. (1993). Big open squares involving some points indicate the halo barium stars, according to Mennessier et al. (1997).
