Description
This table contains the ROSAT North Ecliptic Pole (NEP) Survey X-Ray Source Catalog. The sky around the NEP, at RA (J2000.0) = 18h00m00s, Declination (J2000.0) = +66d33'39", has the deepest exposure of the entire ROSAT All-Sky Survey (RASS). The NEP is an undistinguished region of moderate Galactic latitude, b = 29.8 degrees, and hence it is suitable for compiling statistical samples of both Galactic and extragalactic objects. The authors have made such a compilation in the 80.6 square degrees region surrounding the NEP. Their sample fully exploits the properties of the RASS, since the only criteria for inclusion are source position and significance, and it yields the deepest large solid angle contiguous sample of X-ray sources to date. They find 442 unique sources above a flux limit ~2 x 10<sup>-14</sup> ergs cm<sup>-2</sup> s<sup>-1</sup> in the 0.5-2.0 keV band. In this table, the X-ray properties of these sources as determined from the RASS are presented. These include positions, fluxes, spectral information in the form of hardness ratios, and angular sizes. This table was created by the HEASARC in February 2006 based on a machine-readable version of Table 4 in the above paper which was obtained from the electronic ApJ website.
