Category array_structure_list_axis

Category Description

     Data items in the ARRAY_STRUCTURE_LIST_AXIS category describe
     the physical settings of sets axes for the centres of pixels that
     correspond to data points described in the
     ARRAY_STRUCTURE_LIST category.

     In the simplest cases, the physical increments of a single axis correspond
     to the increments of a single array index.  More complex organizations,
     e.g. spiral scans, may require coupled motions along multiple axes.

     Note that a spiral scan uses two coupled axis, one for the angular
     direction, one for the radial direction.  This differs from a
     cylindrical scan for which the two axes are not coupled into one set.
