* This file is part of McStas  version 1.6, released .
* It provides some data files that may be used with McStas components.
*
* The prefered format is text, with header identified with the '#' character.
* Here are recommended extensions:
*
* lau : Laue pattern file, as issued from Crystallographica.
*       For use with Single_crystal, PowderN, and Isotropic_Sqw.
*       Data: [ h   k   l Mult. d-space 2Theta   F-squared ]
*       Identifier in header: "Format parameters: Crystallographica"
*       Single crystal files may be generated from CIF files via the cif2hkl
*       service at: http://barns.ill.fr/cif2hkl.html
* laz : Powder pattern file, as obtained from Lazy/ICSD.
*       For use with PowderN, Isotropic_Sqw and possibly Single_crystal.
*       Identifier in header: "Format parameters: Lazy"
*       Powder files may be generated from CIF files via the cif2hkl
*       service at: http://barns.ill.fr/cif2hkl.html
* trm : transmission file, typically for monochromator crystals and filters.
*       Data: [ k (Angs-1) , Transmission (0-1) ]
*       Identifier in header: "Format: McStas Reflectivity file"
* rfl : reflectivity file, typically for mirrors and monochromator crystals.
*       Data: [ k (Angs-1) , Reflectivity (0-1) ]
*       Identifier in header: "Format: McStas Transmission file"
* sqw : S(q,omega) files for Isotropic_Sqw component.
*       Data: [q] [omega] [S(q,omega)]
*       Identifier in header: "Sqw data file for Isotropic_Sqw"
