The Polar spacecraft carries three instruments for imaging the auroral oval: the Polar X-Ray Imaging Experiment (PIXIE), the Ultraviolet Imager (UVI), and the Visible Imaging System (VIS). Each of these imagers acquires auroral images from disparate regions of the electromagnetic spectrum and responds to photons produced by the atmospheric impact of precipitating particles of diverse energies. Methods have been developed to deduce the spectral distributions of the electrons producing the emissions in the various wavelength regions measured by the three instruments. The combined analysis of the results from each of the imagers reveals information on the precipitating auroral particles not easily obtained from a single instrument. We present a review of the results from studies incorporating the analysis from combinations of the three instruments and discuss the application of these results to the derivation of various ionospheric parameters.
