Item Description
The real-space residual RSR, as described by Branden and Jones,
evaluated over all atoms in the sugar moiety of the nucleic acid
monomer.
sum|pobs - pcalc|
RSR = ---------------------
sum|pobs + pcalc|
pobs = the density in an "experimental" map
pcalc = 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.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
_struct_mon_details.RSR.
