We study the diffuse emission in 13 far-ultraviolet images taken with the FAUST telescope in order to constrain dust-scattering parameters and search for extragalactic diffuse emission. The images cover more than 600 square degrees and sample both high and low galactic latitudes. We compare the far- ultraviolet emission in these regions with 100 m emission as measured by the Infrared Astronomical Satellite. We compare these 100 am measurements with those from the recent Diffuse Infrared Background Experiment and find that earlier measurements of the Galactic FUV/IR ratio need substantial corrections. We interpret the FUV emission using the Jura model for the light scattered from isolated dust clouds and find values for the dust-scattering parameters in agreement with other studies. Using other analysis techniques, we are unable to constrain or detect significantly an extragalactic component to the diffuse far-ultraviolet emission.
