_reflns_shell.Rmerge_F_all
Name:_reflns_shell.Rmerge_F_all
Alias:
_reflns_shell_Rmerge_F_all
Definition:
The value of Rmerge(F) for all reflections in a given shell.
sum~i~ ( sum~j~ | F~j~ - <F> | )
Rmerge(F) = --------------------------------
sum~i~ ( sum~j~ <F> )
F~j~ = the amplitude of the jth observation of reflection i
<F> = the mean of the amplitudes of all observations of
reflection i
sum~i~ is taken over all reflections
sum~j~ is taken over all observations of each reflection.
Type: Real
Units: none
The permitted range is 0.0 → infinity
