Definition:
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.
Type: float
