Spectral analysis of Lockman Hole
Listed in IVOA Registry (Virtual Observatory)
We present the results of the X-ray spectral analysis of the first deep X-ray survey with the XMM-Newton observatory during Performance Verification.
Description
The X-ray data of the Lockman Hole field and the derived cumulative source counts were reported by Hasinger et al. (2001A&A...365L..45H). We restrict the analysis to the sample of 98 sources with more than 70 net counts (flux limit in the [0.5-7]keV band of 1.6x10^-15^erg/cm^2^/s) of which 61 have redshift identification.
We find no correlation between the spectral index and the intrinsic absorption column density NH and, for both the Type-1 and Type-2 AGN populations, we obtain <Gamma>~=2.
