Description 


              The mean phasing power P for reflections in this shell.

                          sum|Fh~calc~^2^|
               P = (----------------------------)^1/2^
                    sum|Fph~obs~ - Fph~calc~|^2^

               Fph~obs~  = the observed structure factor amplitude of the
                           derivative
               Fph~calc~ = the calculated structure factor amplitude of the
                           derivative
               Fh~calc~  = the calculated structure factor amplitude from the
                           heavy atom model

               sum is taken over the specified reflections
