Spatial Dependence of Spectral Signal Components. Spatial dependence of spectral signal components for a harmonic drive field in combination with a constant gradient selection field. Left: ideal particles. Right: Langevin particles. For these more realistic particles, the spatial response functions extend beyond the range [-A/G; A/G] covered by the FFP motion.
