+You can use **indexamajig** option **--max-mille-level** to reduce the size of
+the calibration data files, at the cost of limiting the maximum refinement

 The default behaviour is to refine only the position components in the x-y
 plane, perpendicular to the beam.  In favourable circumstances, you can add
 option **--out-of-plane** to refine the panel tilts and shifts out of this
