Have seen the real-space correlation used widely judging the map quality. Generally or empirically, in order to say an map (area) has "good" quality, how large should the real space correlation coefficient be? Say, is 0.8 good enough on a residue base? Any references about this will be greatly appreciated!
why don't you just familiarize yourself with the map CC values computed per atom or per residue, for a few different structures at different resolutions? It might take you a few hours but from that point on you will have some reference between the map CC values and actual map appearance. phenix.model_vs_data or phenix.real_space_correlation can compute all these values for you.
I did it at some point to educate myself and never regretted about the time I spent doing this -:)
