|
* \brief Definition of the G4ChannelingFastSimInterpolation class
|
|
* The class includes spline interpolation coefficients for the important functions
|
|
* needed in Channeling FastSimulation model, i.e. electric fields, nuclear and
|
|
* electron densities and minimum energy of ionization. All the functions have
|
|
* transverse coordinates as arguments (x for crystal planes, x and y for crystal axes).
|
|
* All the functions are calculated in the co-rotating reference system (along crystal
|
|
* planes/axes).
