44 * \brief Definition of the G4ChannelingFastSimCrystalData class
45 * The class inherits G4VChannelingFastSimCrystalData containing the data and properties
46 * related to the crystal lattice.
47 * The functions related to the crystal geometry (transformation of coordinates and angles
48 * from the reference system of the bounding box of the local volume to
49 * the crystal lattice co-rotating reference system and vice versa) and
50 * initialization function SetMaterialProperties are compiled in this class.
