+// The class calculates the space point distortions due to the B field
+// shape imperfections using a second order technique based on integrals
+// over Bz (e.g. int By/Bz) obtained via the AliMagF class. The essential
+// input for this class is the magnetic field maps which can be set via the function SetBField.
+// <p>
+// The class allows "effective Omega Tau" corrections.
