General information
Spacegroup name
_symmetry.space_group_name_H-M
P 31
  Hermann-Mauguin space-group symbol. Note that the
  Hermann-Mauguin symbol does not necessarily contain complete
  information about the symmetry and the space-group origin. If
  used, always supply the FULL symbol from International Tables
  for Crystallography Vol. A (2002) and indicate the origin and
  the setting if it is not implicit. If there is any doubt that
  the equivalent positions can be uniquely deduced from this
  symbol, specify the  _symmetry_equiv.pos_as_xyz or
  _symmetry.space_group_name_Hall  data items as well. Leave
  spaces between symbols referring to
  different axes.

Data quality metricsOverall
Low resolution limit [Å] 
_reflns.d_resolution_low
123.600
  The largest value in angstroms for the interplanar spacings
  for the reflection data. This is called the lowest resolution.
High resolution limit [Å] 
_reflns.d_resolution_high
2.300
  The smallest value in angstroms for the interplanar spacings
  for the reflection data. This is called the highest resolution.
Rmerge 
_reflns.pdbx_Rsym_value
0.041
  The R sym value as a decimal number.
  Rmeas -
  Rpim -
  Total number of observations -
Total number unique 
_reflns.number_obs
20826
  The number of reflections in the REFLN list (not the DIFFRN_REFLN
  list) classified as observed (see _reflns.observed_criterion).
  This number may contain Friedel-equivalent reflections according
  to the nature of the structure and the procedures used.

  The mean of the ratio of the intensities to their
  standard uncertainties, <I/sigma(I)>.

93.1
  The percentage of geometrically possible reflections represented
  by reflections that satisfy the resolution limits established
  by _reflns.d_resolution_high and _reflns.d_resolution_low and
