   The real-space residual RSR, as described by Branden & Jones
   (1990), evaluated over all atoms in the side chain of the

         sum|p~obs~ - p~calc~|
   RSR = ---------------------
         sum|p~obs~ + p~calc~|

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

   sum is taken over the specified grid points

   Details of how these maps were calculated should be given
   in _struct_mon_details.RSR. 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
