 The values of '_diffrn_reflns_theta_max' and '_diffrn_reflns_theta_full'
 are  reported as equal. However, the associated reported values of
 '_diffrn_measured_fraction_theta_max'  and
 '_diffrn_measured_fraction_theta_full' are not equal. This is inconsistent.
 CIF Dataname Definitions:
 _diffrn_measured_fraction_theta_max:
    Fraction of unique (symmetry-independent) reflections measured out to
    '_diffrn_reflns_theta_max'.
 _diffrn_measured_fraction_theta_full:
    Fraction of unique (symmetry-independent) reflections measured out to
    '_diffrn_reflns_theta_full'.
 _diffrn_reflns_theta_max:
   Maximum theta angle in degrees for the measured intensities. The fraction
   of unique reflections measured out to this angle is given by
   '_diffrn_measured_fraction_theta_max'.
 _diffrn_reflns_theta_full:
    The theta angle (in degrees) at which the measured reflection count is
    close to complete. The fraction of unique reflections measured out to
    this angle is given by '_diffrn_measured_fraction_theta_full'.
