We have used the reprocessed IUE archives to revisit ultraviolet spectral imaging results obtained using the original data. The reprocessed data have higher signal-to-noise and a more reliable wavelength scale. Inaccuracies in the wavelength scale prevented a unique interpretation of the single-lined systems, such as EI Eri and HD 199178. We are reanalyzing these spectra using improved data and computational techniques. We will present a detailed comparison of spatial maps derived using the reprocessed and original data. We can use these maps as inputs to chromospheric and flare models.
