_symmetry.space_group_name_H-M

  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.

_cell.length_{a,b,c} _cell.angle_{alpha,beta,gamma}

  angstroms.

  Unit-cell length c corresponding to the structure reported in
  angstroms.

  Unit-cell angle alpha of the reported structure in degrees.

  Unit-cell angle beta of the reported structure in degrees.

  Unit-cell angle gamma of the reported structure in degrees.

_diffrn_radiation_wavelength.wavelength

  The radiation wavelength in angstroms.

_reflns.d_resolution_low _reflns_shell.d_res_low

  The largest value in angstroms for the interplanar spacings
  for the reflection data. This is called the lowest resolution.

  The highest value in angstroms for the interplanar spacings
  for the reflections in this shell. This is called the lowest
  resolution.

_reflns.d_resolution_high _reflns_shell.d_res_high

  The smallest value in angstroms for the interplanar spacings
  for the reflection data. This is called the highest resolution.

  The smallest value in angstroms for the interplanar spacings
  for the reflections in this shell. This is called the highest
  resolution.

  The R value for merging intensities satisfying the observed
  criteria in this data set.

  The value of Rmerge(I) for reflections classified as 'observed'

  reflection i
  
  sum~i~ is taken over all reflections
  sum~j~ is taken over all observations of each reflection

_reflns.number_obs

  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.

_reflns.pdbx_netI_over_sigmaI _reflns_shell.meanI_over_sigI_obs

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

  The ratio of the mean of the intensities of the reflections
  classified as 'observed' (see _reflns.observed_criterion) in
  this shell to the mean of the standard uncertainties of the
  intensities of the 'observed' reflections in this
  shell.

_reflns.percent_possible_obs _reflns_shell.percent_possible_all

  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
  the observation limit established by
  _reflns.observed_criterion.

  The percentage of geometrically possible reflections represented
  by all reflections measured for this shell.
