Resolution

Resolution is an average value for the uncertainty of atomic positions in a crystallographic model. High values for resolution (e.g. 5.0 Å) mean high uncertainty, and low values (e.g. 1.0 Å) mean much less uncertainty. 2.05 Å is the median resolution for X-ray crystallographic results in the Protein Data Bank (43,066 on May 2, 2008).

The uncertainty for each atom is quantitated in its temperature value.
