1992ApJS...80..531F AN X-RAY CATALOG AND ATLAS OF GALAXIES G. FABBIANO, D.-W. KIM, AND G. TRINCHIERI Received 1991 May 20; accepted 1991 September 4 ABSTRACT We present an X-ray catalog and atlas of galaxies observed with the Einstein Observatory imaging instruments (IPC and HRI). The catalog comprises 493 galaxies, including targets of pointed observations, and RSA or RC2 galaxies serendipitously included in Einstein fields. A total of 450 of these galaxies were imaged well within the instrumental fields, resulting in 238 detections and 212 3{sigma} upper limits. The other galaxies were either at the edge of the visible field of view or confused with other X-ray sources. For these we also give a rough measure of their X-ray emission. The atlas shows X-ray contour maps of detected galaxies superposed on optical photographs and gives azimuthally averaged surface brightness profiles of galaxies detected with high signal-to-noise ratio. Subject headings: atlases - catalogs - Galaxy: structure - X-rays: galaxies
