0028 // Class description:
0029 //
0030 // Class describing the DELPHI magnetic field. This axial symmetry
0031 // field mainly directed along Z axis. The function MagneticField(yTrack,B)
0032 // calculates the magnetic induction vector B in point corresponding to
0033 // yTrack according to parametrization given in:
0034 //   P.Billoir, Precise tracking in a quasi-honogeneous magnetic field,
0035 //              DELPHI 87-6 PROG 65, 1987.
