Category ARRAY_STRUCTURE_LIST_AXIS
Name:'ARRAY_STRUCTURE_LIST_AXIS'
Parent category:
ARRAY_GROUP
Definition:
Data items in the ARRAY_STRUCTURE_LIST_AXIS category describe
the physical settings of sets of 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 axes: one for the angular
direction and one for the radial direction. This differs from a
cylindrical scan for which the two axes are not coupled into one
set.
Axes may be specified wither for an entire array or for just a section
of an array.
Category is of type Loop
