J/A+A/278/379    X-ray Emission from Abell Clusters of Galaxies  (Briel+ 1993)

X-ray Emission from a Complete Sample of Abell Clusters of Galaxies Briel U.G., Henry J.P. <Astron. Astrophys. 278, 379 (1993)> =1993A&A...278..379B
ADC_Keywords: X-ray sources ; Clusters, galaxy Keywords: cosmology: observations - galaxies: clustering - X-rays: galaxies Description: The results of ROSAT All-Sky Survey (RASS, see cat. IX/10) have been used to investigate the X-ray properties of a complete sample of Abell clusters within a 561 square degree region at high galactic latitude; the mean redshift of the sample is 0.17.
