mFo − DFc OMIT density maps of Phe92 (chain A) from the structure of a potassium ion channel at atomic resolution contoured at a level of 2.6σ. Panels (a), (b) and (c) show conventional OMIT maps, while panels (d), (e) and (f) show polder OMIT maps. In panels (a) and (d), both conformations of Phe92 have been omitted; in panels (b) and (e), the A conformation of Phe92 has been omitted; and in panels (c) and (f), the B conformation of Phe92 has been omitted. In panel (g), a composite polder OMIT map is shown.
