Item Description
The pixel-centre-to-pixel-centre distance for a one-step
change in the setting of the specified axis in millimetres.
This is meaningful only for 'constant velocity' spiral scans
or for uncoupled angular scans at a constant radius
(cylindrical scans) and should not be specified for cases
in which the angle between pixels (rather than the distance
between pixels) is uniform.
See _array_structure_list_axis.angle_increment.
