-// //
-// Wrapper for the set of mag.field parameterizations by Chebyshev polinomials //
-// To obtain the field in cartesian coordinates/components use //
-// Field(float* xyz, float* bxyz); //
-// For cylindrical coordinates/components: //
-// FieldCyl(float* rphiz, float* brphiz) //
-// //
-// For the moment only the solenoid part is parameterized in the volume defined //
-// by R<500, -550<Z<550 cm //
-// //
-// The region R<423 cm, -343.3<Z<481.3 for 30kA and -343.3<Z<481.3 for 12kA //
-// is parameterized using measured data while outside the Tosca calculation //
-// is used (matched to data on the boundary of the measurements) //
-// //
-// If the querried point is outside the validity region no the return values //
-// for the field components are set to 0. //
