Can only be used in combination: fit cell, fit orientation, fit beam, or fit distance.
Adds the cell parameters to the list of parameters to be refined. The program takes the specified Bravais lattice into account to decide which parameters can be refined. After each refinement cycle, the cell axes will be rescaled to give the cell volume as specified by the volume keyword.
Adds the crystal orientation parameters 
, 
, and
to the list of parameters to be refined.
Adds the origin shift parameters 
to the list
of parameters to be refined.
Adds the crystal to detector distance to the list of parameters to be refined.
