VizieR Online Data Catalog: Swift X-ray Telescope Cluster Survey (Tundo+, 2012)

We present the 72 SXCS sources. For each source the identification Id, equatorial coordinates, exposure time corrected for vignetting, Galactic absorption, extraction radius R_ext, aperture photometry within R_ext and total energy flux are given. We remark that the photometry of our extended sources refers to the extraction radius R_ext defined as the radius where the fitted surface brightness falls below the measured local background, while the total energy flux include the correction factor c_f for the flux lost beyond R_ext.
