_reflns_shell.Rmerge_I_all
Name:_reflns_shell.Rmerge_I_all
Alias:
_reflns_shell_Rmerge_I_all
Definition:
The value of Rmerge(I) for all reflections in a given shell.
sum~i~ ( sum~j~ | I~j~ - <I> | )
Rmerge(I) = --------------------------------
sum~i~ ( sum~j~ <I> )
I~j~ = the intensity of the jth observation of reflection i
<I> = the mean of the intensities 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
