The Far Ultraviolet Spectroscopic Explorer (FUSE) satellite will make high spectral resolving power measurements of astrophysical objects in the 905 - 1187Åwavelength region from low-earth orbit. The FUSE science pipeline will turn the complex, two-dimensional astigmatic detector data generated by the instrument into calibrated, one-dimensional spectra. In preparation for this task, we have analyzed data taken during ground characterization of the instrument. An automated spectral line identification program has been used to determine the nonlinear instrument wavelength scale, and raytracing models have been used to develop model point spread functions in order to reduce the spectra to one dimension. Sample spectra taken during ground testing will be presented in both raw and reduced form.
