The Northern ROSAT All-Sky (NORAS) Galaxy Cluster Survey. I. X-Ray Properties of Clusters Detected as Extended X-Ray Sources*
Hans Böhringer,Wolfgang Voges,John P. Huchra,Brian McLean,Riccardo Giacconi,Piero Rosati,R. Burg,J. Mader,Peter Schuecker,D. Simic,Stefanie Komossa,Thomas H. Reiprich,J. Retzlaff,Joachim Trümper +13 more
TL;DR: In this article, the authors used a new X-ray source characterization technique, termed growth curve analysis (GCA), to provide more precise values for the Xray flux and source extent than obtained from the standard processing.

The Northern ROSAT All-Sky (NORAS) Galaxy Cluster Survey I: X-ray Properties of Clusters Detected as Extended X-ray Sources
Hans Boehringer,Wolfgang Voges,John P. Huchra,Brian McLean,Riccardo Giacconi,Piero Rosati,R. Burg,J. Mader,Peter Schuecker,D. Simic,Stefanie Komossa,Thomas H. Reiprich,J. Retzlaff,Joachim E. Truemper +13 more
TL;DR: In this paper, a sample of 495 X-ray sources found to show extended Xray emission in the first processing of the ROSAT All-Sky Survey was assembled for the construction of an Xray selected sample of galaxy clusters for cosmological studies.
