Figure 3: The calculated total DOS and atom-projected PDOS plots for CoMnTiSi alloy with 4% Co-Mn anti-site disorder.
From: Anti-site-induced diverse diluted magnetism in LiMgPdSb-type CoMnTiSi alloy

What the red arrows denote is antibonding states generated by the hybridization of Co(C) at the anti-site and Co(A) at the normal site.
