Description

              The real-space (linear) correlation coefficient RSCC, as
               described by Jones et al., evaluated over all atoms in the
               main chain of the monomer.

                      sum|p~obs~ - | * sum|p~calc~ - |
               RSCC = -------------------------------------------------
                            [ sum|p~obs~  -  |^2^
                            * sum|p~calc~ - |^2^ ]^1/2^

               p~obs~  = the density in an "experimental" map
               p~calc~ = the density in a "calculated" map

               sum is taken over the specified grid points

               The details of how these maps were calculated should be described
               in _struct_mon_details.RSCC. < > indicates an average and the
               sums are taken over all map grid  points near the relevant atoms.
               The radius for including grid points in the calculation should
               also be given in _struct_mon_details.RSCC.
