Beginning of ReadMe : IX/18 EINSTEIN extended source survey (EXSS) (Oppenheimer+ 1997) ================================================================================ A survey of the EINSTEIN IPC Database for extended X-ray sources. Oppenheimer B.R., Helfand D.J., Gaidos E.J. <Astron. J. 113, 2134-2146 (1997)> =1997AJ....113.2134O (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: X-ray sources ; Clusters, galaxy ; Mission_Name: Einstein Description: This catalog contains sources from data collected by the IPC on board the EINSTEIN Observatory. This survey is designed to find extended sources and diffuse emission rather than point sources. In addition, the source detection algorithm is substantially improved over that used by EMSS. Sources were searched using circular apertures up to 6.1arcmin. The catalog contains 1326 extended source candidates at high galactic latitude (|b| > 20deg).
