mosaic_AB  arcmin,arcmin,1,1,1,1,1,1  In Plane mosaic rotation and plane vectors (anisotropic), mosaic_A, mosaic_B, A_h,A_k,A_l, B_h,B_k,B_l. Puts the crystal in the inplane mosaic state. Vectors A and B define plane in which the crystal roation is defined, and mosaic_A, mosaic_B, denotes the resp. mosaicities (gaussian RMS) with respect to the the two reflections chosen by A and B (Miller indices).

sqw  0  
geometry  string  Name of an Object File Format (OFF) or PLY file for complex geometry. The OFF/PLY file may be generated from XYZ coordinates using qhull/powercrust.  0 
qwidth  0.05  
xwidth  m  Width of crystal.  0 
yheight  m  Height of crystal.  0 
zdepth  no extinction simulated  [m] Depth of crystal  0 
radius  m  Outer radius of sample in (x,z) plane.  0 
delta_d_d  1  Lattice spacing variance, gaussian RMS.  1e4 
mosaic  arcmin  Isotropic crystal mosaic, gaussian RMS. Puts the crystal in the isotropic mosaic model state, thus disregarding other mosaicity parameters.  1 
mosaic_a  arcmin  Horizontal (rotation around lattice vector a) mosaic (anisotropic), gaussian RMS. Put the crystal in the anisotropic crystal vector state. I.e. model mosaicity through rotation around the crystal lattice vectors. Has precedence over inplane mosaic model.  1

barns  1  Flag to indicate if F^2 from 'reflections' is in barns or fm^2. barns=1 for laz and isotropic constant elastic scattering (reflections=NULL), barns=0 for lau type files.  0
