"Through direct and lattice independent tracking we show how the polarization aperture can be greatly expanded by modifying the 453-nu intrinsic spin resonance next to the main 393+nu resonance. We also explore the conjecture that the structure of the aperture is related to the area of the parametric resonance regions based on the new formulation for the T-BMT equation (given in my recent PRSTAB paper http://journals.aps.org/prstab/pdf/10.110/PhysRevSTAB.18.014001) and how this might explain some of the apparent structure in the polarization profile measurements."
