Lockman Hole Field XMM-Newton X-Ray Point Source Catalog
Listed in NASA Data Portal
This table contains the results of a detailed X-ray spectral analysis of a sample of 123 X-ray sources detected with XMM-Newton in the Lockman Hole field.
Description
This is the deepest observation carried out as yet with XMM-Newton with more that 600 ks of good EPIC-pn data.There are spectra with good signal to noise (>500 source counts) for all objects down to 0.2 - 12 keV fluxes of 5 x 10<sup>-15</sup> erg/cm<sup>2</sup>/s (the flux limit is 6 x 10<sup>-16</sup> erg/cm<sup>2</sup>/s in the 0.5 - 2.0 and 2 - 10 keV bands).
At the time of the analysis, the authors had optical spectroscopic identifications for 60% of the sources, 46 being optical type-1 AGN and 28 optical type-2 AGN. Using a single power law model, their sources' average spectral slope hardens at faint 0.5 - 2 keV fluxes but not at faint 2 - 10 keV fluxes. This table was created by the HEASARC in June 2007 based on <a href="cdsarc.cds.unistra.fr/ftp/cats/J/A+A/444/79">CDS Catalog J/A+A/444/79</a>, file table8.dat.
