Description:
This paper presents consistently reduced UV continuum flux densities amd spectra indices derived from all 499 usable archived IUE observations of blazars made through mid-1991. The extraction of 1D spectra and the measurement of spectral parameters are discussed. A detailed error analysis is presented, including a discussion of the difference in the calibration between the IUE long- and short-wavelength cameras. The resulting data are presented in tabular and graphical form and are available by electronic mail as well. These results will be most useful for variability studies, but can also be used to characterize the broad-band energy distributions and to compare blazar properties with those of other AGN. This is the first in a series of papers, in which extracted spectral parameters will be published for the over 4500 spectra of AGN in the IUE archives.
