ROSAT 13-hour Field XMM-Newton X-Ray Source Catalog
Listed in NASA Data Portal
This table contains the results of a deep X-ray survey conducted with XMM-Newton, centered on the UK ROSAT 13-hours deep field area.
Description
This region covers 0.18 square degrees, and is the first of the two areas covered with XMM-Newton as part of an extensive multi-wavelength survey designed to study the nature and evolution of the faint X-ray source population. This table contains the final catalog of 225 sources.
Within the central 9 arcminutes, 68% of the source positions are accurate to 2 arcseconds, making optical follow-up relatively straightforward. The authors construct the N(>S) relation in four energy bands: 0.2-0.5, 0.5-2, 2-5 and 5-10 keV. In all but the highest energy band, they find that the source counts can be represented by a double power law with a bright-end slope consistent with the Euclidean case and a break around 10<sup>-14</sup> erg cm<sup>-2</sup> s<sup>-1</sup>.

Below this flux, the counts exhibit a flattening. The 13-hours deep field is centered on the sky coordinates RA(J2000) = 13 34 37.1, Dec (J2000) = +37 53 02.2. The XMM-Newton observations were carried out in three separate revolutions during June 2001 for a total exposure time of 200ks.
Approximately 40% of the total observation time was affected by high particle background flares, arising from soft protons hitting the detector. The data were therefore temporally filtered to remove these high-background periods. Filtering reduced the total useful exposure time from ~200 ks to ~120 ks.
This table was created by the HEASARC in August 2007 based on <a href="cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/362/1371">CDS catalog J/MNRAS/362/1371</a> file table9.dat. This is a service provided by NASA HEASARC .
