J/ApJS/92/53 J/ApJS/92/53 Einstein database of quasars. I. B Wilkes H Tananbaum D M Worrall Y Avni M S Oey J Flanagan Astrophys. J. Suppl. Ser. 92 53 1994 1994ApJS...92...53W galaxies: Seyfert quasars: general X-rays: galaxies We present the first volume of the Einstein quasar database. The database includes estimates of the X-ray count rates, fluxes, and luminosities for 514 quasars and Seyfert 1 galaxies observed with the Imaging Proportional Counter (IPC) aboard the Einstein Observatory. All were previously known optically selected or radio-selected objects, and most were targets of the X-ray observations. The X-ray properties of the AGNs have been derived by reanalyzing the IPC data in a systematic manner to provide a uniform database for general use by the astronomical community. We use the database to extend earlier quasar luminosity studies which were made using only a subset of the currently available data. The database can be accessed on Internet via the SAO Einstein on-line system ("Einline") and is available in ASCII format on magnetic tape and DOS diskette.
