  A new method is presented for modeling the transformation between two
polarimetric pulse profiles in the Fourier domain. In practice, one is a
well-determined standard with high signal-to-noise ratio and the other is an
observation that is to be fitted to the standard. From this fit, both the
longitudinal shift and the polarimetric transformation between the two profiles
are determined. Arrival time estimates derived from the best-fit longitudinal
shift are shown to exhibit greater precision than those derived from the total
intensity profile alone. In addition, the polarimetric transformation obtained
through this method may be used to completely calibrate the instrumental
response in observations of other sources.
