1994ApJS...92...53W THE EINSTEIN DATABASE OF IPC X-RAY OBSERVATIONS OF OPTICALLY SELECTED AND RADIO-SELECTED QUASARS. I. BELINDA J. WILKES, HARVEY TANANBAUM, D. M. WORRALL, YORAM AVNI, M. S. OEY, AND JOAN FLANAGAN Received 1993 April 19, accepted 1993 August 26 ABSTRACT 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 ([PC) aboard the Einstein Observatory. All were previously known optically selected or radio-selected objects, and most were the 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. Subject headings: galaxies: Seyfert - quasars: general - X-rays: galaxies
