A sensible definition of high resolution would be that resolution at
which the structure is computationally over-determined, which is about
2 angstroms or better for a complete data set. This would also be a
sensible definition for what is called atomic resolution, because the
atoms are resolved as spheres or better, so that the position is
over-determined.
