Displacing the magnets or moving the orbit to displace the beam in the magnets in an antisymmetric way creates a dispersion wave around the ring. This can be used to correct the vertical dispersion in LER without changing the local coupling. Results from simulations are shown.2 pages, 2 figures, LaTeX, poster at EPAC 2000Accelerator Physicstext
