Oops I am outdated: Axel just emailed me that he describes an improved
coordinate estimate beyond the Rayleigh criterion in his recent paper
Schroder GF, Levitt M, & Brunger AT (2010) Super-resolution biomolecular
crystallography with low-resolution data. Nature 464(7292), 1218-1222.
For the deformable elastic network (DEN) refinement, see his ref 14
Schroder GF, Brunger AT, & Levitt M (2007) Combining efficient
conformational sampling with a deformable elastic network model facilitates
structure refinement at low resolution. Structure 15(12), 1630-1641.
