[55.15] Ultraviolet Lightcurve Internet Database of Active Galactic Nuclei

J. Dunn, D. M. Crenshaw (Georgia State University), B. Jackson (Georgia Tech University)

Using the Multimission Archives at Space Telescope (MAST), we have extracted lightcurve information on 182 Seyfert Galaxies that have been observed with the International Ultraviolet Explorer (IUE) and the Faint Object Spectrograph (FOS). These lightcurves have been determined in two different wavelength regions of the spectrum, ranging from 1100 /AA - 3000 /AA, using the SWP, LWR, and the LWP cameras on IUE and the G130H, G190H, and G270H gratings of FOS. We measured small regions (between 25 /AA and 100 /AA) of the spectrum's continuum flux, taken in the rest frame of the observed galaxy, to describe the flux level of a galaxy at various points in time. The data we have extracted and basic principle information provided by the NASA Extragalactic Database (NED) will be made available via the Internet.
