Mosaic single crystal with multiple scattering vectors, optimised for speed
with large crystals and many reflections.

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).  Mosaic_AB_Undefined 
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) or PLY file for complex geometry. The OFF/PLY 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 
mosaic_b  arc minutes  Vertical (rotation around lattice vector b) mosaic (anisotropic), gaussian RMS.  1 
mosaic_c  arc minutes  Outofplane (Rotation around lattice vector c) mosaic (anisotropic), gaussian RMS  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 
ax  AA or AA^1  Coordinates of first (direct/recip) unit cell vector  0 
ay    a on y axis  0 
az    a on z axis  0 
bx  AA or AA^1  Coordinates of second (direct/recip) unit cell vector  0 
by    b on y axis  0 
bz    b on z axis  0 
cx  AA or AA^1  Coordinates of third (direct/recip) unit cell vector  0 
cy    c on y axis  0 
cz    c on z axis  0 
p_transmit  1  Monte Carlo probability for neutrons to be transmitted without any scattering. Used to improve statistics from weak reflections  1 
sigma_abs  barns  Absorption crosssection per unit cell at 2200 m/s  0 
sigma_inc  barns  Incoherent scattering crosssection per unit cell Use 1 to unactivate  0 
aa  deg  Unit cell angles alpha, beta and gamma. Then uses norms of vectors a,b and c as lattice parameters  0 
bb  deg  Beta angle  0 
cc    Gamma angle [deg].  0 
order  1  Limit multiple scattering up to given order (0: all, 1: first, 2: second, ...)  0 
RX  m  Radius of horizontal along X lattice curvature. flat for 0  0 
RY  m  Radius of vertical lattice curvature. flat for 0  0 
RZ  m  Radius of horizontal along Z lattice curvature. flat for 0  0 
powder  1  Flag to indicate powder mode, for simulation of DebyeScherrer cones
via random crystallite orientation. A powder texture can be
approximated with 0  0 
PG  1  Flag to indicate "Pyrolytic Graphite" mode, only meaningful with
choice of Graphite.lau, models PG crystal. A powder texture can be
approximated with 0  0
