[phenixbb] Weighting in phenix.real_space_refine

Hi all, How does phenix.real_space_refine deal with restraint weighting? Looking at the output of the program, I get the impression that it splits the model up into different chunks, and alters weights locally based on some model/map correlation metric - is this the case (and are there more specific details available), or how does it work otherwise? Cheers, Oliver.
