// class description
//
// This class is an interface to G4StaticSandiaData.
// it provides - Sandia coeff for an element, given its Z
//             - sandia coeff for a material, given a pointer to it
//

//
// History:
//
// 10.06.97 created. V. Grichine
// 18.11.98 simplified public interface; new methods for materials.  mma
// 30.01.01 major bug in the computation of AoverAvo and in the units (/g!)
//          in GetSandiaCofPerAtom(). mma
// 03.04.01 fnulcof[4] added; returned if energy < emin
// 05.03.04 V.Grichine, new methods for old sorting algorithm for PAI model
