Hi,
We are attempting to address a referees comment concerning our data/parameter ratio for a 3.4 A structure. Although the ratio is only 0.5, the R/Rfree is 25/29, which seems acceptable. Ideally I would like to include a reference showing a graph or table of data:parameter vs resolution but I have been unable to find such a paper. Please could someone point me in the right direction.
Thanks in advance
Hugh
P.S. It would be nice to know if this table has been published
http://www-structmed.cimr.cam.ac.uk/Course/Basic_refinement/Refinement.html
or something similar to this, which includes higher resolution structures
