Bear in mind that the resolution value represents the "best" (most ordered) parts of a crystal, and that other parts may have poorer quality. The [[temperature value]] for each atom in a crystallographic model indicates the clarity of its electron density map. | Bear in mind that the resolution value represents the "best" (most ordered) parts of a crystal, and that other parts may have poorer quality.
