Item Description

The value of _diffrn_detector.number_of_axes gives the number of axes of the positioner for the detector identified by _diffrn_detector.id. The word 'positioner' is a general term used in instrumentation design for devices that are used to change the positions of portions of apparatus by linear translation, rotation or combinations of such motions. Axes which are used to provide a coordinate system for the face of an area detector should not be counted for this data item. The description of each axis should be provided by entries in DIFFRN_DETECTOR_AXIS.
