Abstract
The radio-quiet neutron star 1E1207.4-5209 was the target of a 260 ks XMM-Newton observation, that yielded, as a by product, a harvest of about 200 serendipitous X-ray sources above a limiting flux of 2 $\times$ 10-15 erg cm-2 s-1 in the 0.3-8 keV energy range. In view of the intermediate latitude of our field ( $b\simeq 10^{\circ}$), it comes as no surprise that the log N-log S distribution of our serendipitous sources is different from those measured either in the Galactic Plane or at high galactic latitudes. Here we concentrate on analyzing of the brightest sources in our sample, which unveiled a previously unknown Seyfert-2 galaxy.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
