Mosaic single crystal with multiple scattering vectors.

Name  Unit  Description  Default 

mosaic_AB  arc_minutes, arc_minutes,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).  {0

reflections  string  File name containing structure factors of reflections. Use empty ("") or NULL for incoherent scattering only  0 
geometry  str  Name of an Object File Format (OFF) file for complex geometry. The OFF file may be generated from XYZ coordinates using qhull/powercrust  0 
xwidth  m  Width of crystal  0 
yheight  m  Height of crystal  0 
zdepth  m  Depth of crystal (no extinction simulated)  0 
radius  m  Outer radius of sample in (x,z) plane  0 
delta_d_d  1  Lattice spacing variance, gaussian RMS  1e4 
mosaic  arc minutes  Crystal mosaic (isotropic), gaussian RMS. Puts the crystal in the isotropic mosaic model state, thus disregarding other mosaicity parameters.  1 
mosaic_a  arc minutes  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
