// class G4DELPHIMagField
//
// Class description:
//
// Class describing the DELPHI magnetic field. This axial symmetry
// field mainly directed along Z axis. The function MagneticField(yTrack,B)
// calculates the magnetic induction vector B in point corresponding to
// yTrack according to parametrization given in:
//   P.Billoir, Precise tracking in a quasi-honogeneous magnetic field,
//              DELPHI 87-6 PROG 65, 1987.
 
// History:
// 3.2.97 - V. Grichine, created.
