摘要：

Using the Multimission Archive at STScI ( MAST), we have extracted spectra and determined continuum light curves for 175 Seyfert galaxies that have been observed with the International Ultraviolet Explorer and the Faint Object Spectrograph on the Hubble Space Telescope. To obtain the light curves as a function of Julian Date, we used fixed bins in the object's rest frame and measured small regions ( between 30 and 60 angstrom) of each spectrum's continuum flux in the range 1150 to 3200 angstrom. We provide access to the UV light curves and other basic information about the observations in tabular and graphical form via the Internet at http:// www. chara. gsu. edu/ PEGA/ IUE.
