  For high-resolution separators like the projected Super-FRS at FAIR, an
adapted and accurate ion-optical model considering realistic B-dependent magnet
parameters is crucial in achieving the desired parameters (e.g. resolution) and
to enable a fast optimization. Starting from the magnetic field measurements
and simulations, rigidity-dependent Taylor transfer maps are generated for the
Super-FRS preseparator dipole magnets. The effects of the magnetic saturation
in the steel yoke on the image aberrations are analyzed.
