Image dictionary (imgCIF) version 1.3.2




   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.
