1994ApJS...94..517M HIGH-ENERGY SPECTRA OF ACTIVE GALACTIC NUCLEI. I. THE CATALOG G. MALAGUTI, L. BASSAM, AND E. CAROLI Received 1993 June 7; accepted 1994 March 23 ABSTRACT This paper presents a catalog of high-energy spectra (E >= 0.01 keV) of active galactic nuclei (AGNs). The catalog contains 209 objects (140 Seyfert galaxies, 65 quasars, and 4 objects otherwise classified), for a total of 1030 spectra. Most of the data have been collected from the literature over a period spanning more than 20 yr starting from the early 1970s up to the end of 1992. For a number of objects (17), EXOSAT/ME data have been extracted and analysed, and the 27 spectra obtained have been added to the database. For each object we report individual observation spectral fit parameters using a power-law model corrected for cold gas absorption along the line of sight (photon index, 1 keV intensity and hydrogen column density), plus other relevant data. It is hoped that this database can become a useful tool for the study of the AGN phenomenon in its various aspects. Subject headings: catalogs - galaxies: active - galaxies: Seyfert - quasars: general - X-rays: galaxies
