_phasing_MIR_shell.R_kraut

Definition:

   Residual factor R~kraut~ for general reflections in this shell.

              sum|Fph~obs~ - Fph~calc~|
   R~kraut~ = -------------------------
                    sum|Fph~obs~|

   Fph~obs~  = the observed structure-factor amplitude of the
               derivative
   Fph~calc~ = the calculated structure-factor amplitude of the
               derivative

   sum is taken over the specified reflections
