    "abstract": "A fitting method to reconstruct the momentum and direction of charged\nparticles in slightly inhomogeneous magnetic fields is presented in detail. For\nmagnetic fields of the order of 1 T and inhomogeneity gradients as large as 1\nT/m the typical momentum bias due to the proposed approximations is of the\norder of few MeV, to be compared with scattering components of the order of 20\nMeV or even larger. This method is currently being employed in the\nreconstruction programs of the AMS experiment.",
