_reflns_class.R_factor_all
Name:_reflns_class.R_factor_all
Alias:
_reflns_class_R_factor_all
Definition:
Residual factor for reflections in this class used in refinement.
sum | F(meas) - F(calc) |
R(F all) = ------------------------
sum | F(meas) |
F(meas) = the measured structure-factor amplitudes
F(calc) = the calculated structure-factor amplitudes
and the sum is taken over the specified reflections.
Type: Real
Units: none
The permitted range is 0.0 → infinity
