_atom_site_aniso.beta_22_su
Name:_atom_site_aniso.beta_22_su
Alias:
_atom_site_aniso_beta_22_su
Definition:
These are the standard uncertainty values (s.u.) for the standard
form of the β^ij^ anisotropic atomic displacement components (see
aniso_betaIJ). Because these values are _type.purpose Measurand, the
s.u. values may in practice be auto generated as part of the
β^ij^ calculation.
Type: Real
Units: none
