The Northern <i>ROSAT</i> All‐Sky (NORAS) Galaxy Cluster Survey. I. X‐Ray Properties of Clusters Detected as Extended X‐Ray Sources

In the construction of an X-ray-selected sample of galaxy clusters for cosmological studies, we have assembled a sample of 495 X-ray sources found to show extended X-ray emission in the first processing of the ROSAT All-Sky Survey. The sample covers the celestial region with declination δ ≥ 0° and Galactic …
