_diffrn_reflns.Laue_measured_fraction_full

Name:
_diffrn_reflns.Laue_measured_fraction_full

Alias:
_diffrn_reflns_Laue_measured_fraction_full

Definition:

   
    Fraction of Laue group unique reflections (symmetry-independent in
    the Laue group) measured out to the resolution given in
    _diffrn_reflns.resolution_full or _diffrn_reflns.theta_full.
    The Laue group always contains a centre of symmetry so that
    the reflection h,k,l is always equivalent to the reflection
    -h,-k,-l even in space groups without a centre of symmetry.
    This number should not be less than 0.95, since it represents
    the fraction of reflections measured in the part of the
    diffraction pattern that is essentially complete.

Type: Real

Units: none


The permitted range is 0.95 → 1.0
