_atom_site.refinement_flags_posn

Name:
_atom_site.refinement_flags_posn

Alias:
_atom_site_refinement_flags_posn

Definition:

   
     A code which indicates the refinement restraints or constraints
     applied to the positional coordinates of this site.

Type: Text

The data value must be one of the following:

`.`	no constraints on positional coordinates

`D`	distance or angle restraint on positional coordinates

`G`	rigid-group refinement of positional coordinates

`R`	riding-atom site attached to non-riding atom

`S`	special-position constraint on positional coordinates

`DG`	combination of the above constraints

`DR`	combination of the above constraints

`DS`	combination of the above constraints

`GR`	combination of the above constraints

`GS`	combination of the above constraints

`RS`	combination of the above constraints

DGR combination of the above constraints

DGS combination of the above constraints

DRS combination of the above constraints

GRS combination of the above constraints

DGRS combination of the above constraints
