Resolution

In crystal structure determination, the  term  resolution is used to describe the  ability  to distinguish between neighboring  features  in an electron density map. By convention, it is defined as the minimum plane spacing given by Bragg's law for a particular set of X-ray  diffraction  intensities. The resolution improves with an increase in the maximum value of (\sin\, \theta)/\lambda at which reflections are measured.
