_axis.system

Name:
_axis.system

Definition:

   
    The value of  _axis.system specifies the coordinate
    system used to define the axis: 'laboratory', 'direct',
    'orthogonal', 'reciprocal' or 'abstract'.

Type: Code


The data value must be one of the following:


laboratory 		the axis is referenced to the imgCIF standard laboratory Cartesian coordinate system

direct 		the axis is referenced to the direct lattice

orthogonal 		the axis is referenced to the cell Cartesian orthogonal coordinates

reciprocal 		the axis is referenced to the reciprocal lattice

abstract 		the axis is referenced to abstract Cartesian cooridinate system

Enumeration default: laboratory
