calculate perfect crystal reflectivity. xinpro calculates the diffracted and transmitted profiles in reflection (Bragg) and transmission (Laue) geometries for plane perfect crystals.
NOTE: This is an standalone program developed at the ESRF optics group. XOP developers recommend to use xcrystal, as it has a wider functionality and uses DABAX files.
Bug: The Debye-Waller model diverges for zero Kelvin.
