cds-question@unistra.frx-ray-sourcessurveysWe report results of a serendipitous hard X-ray (3-20keV), nearly all-sky (|b|>10{deg}) survey based on RXTE/PCA observations performed during satellite reorientations in 1996-2002. The survey is 80% (90%) complete to a 4{sigma} limiting flux of ~1.8 (2.5)x10^-11^erg/s/cm^2^ in the 3-20keV band. The achieved sensitivity in the 3-8keV and 8-20keV subbands is similar to and an order of magnitude higher than that of the previously record HEAO-1 A1 and HEAO-1 A4 all-sky surveys, respectively. A combined 7x10^3^~sq.deg area of the sky is sampled to flux levels below 10^-11^erg/s/cm^2^ (3-20keV). In total 294 sources are detected and localized to better than ~1{deg}. 236 (80%) of these can be confidently associated with a known astrophysical object; another 22 likely result from the superposition of 2 or 3 closely located known sources. 35 detected sources remain unidentified, although for 12 of these we report a likely soft X-ray counterpart from the ROSAT all-sky survey bright source catalog. Of the reliably identified sources, 63 have local origin (Milky Way, LMC or SMC), 64 are clusters of galaxies and 100 are active galactic nuclei (AGN). The fact that the unidentified X-ray sources have hard spectra suggests that the majority of them are AGN, including highly obscured ones (N_H_>10^23^cm^-2^). For the first time we present a logN-logS diagram for extragalactic sources above 4x10^-12^erg/s/cm^2^ at 8-20keV.2004A&A...418..927Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/418/927CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/418/927https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/418/927http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/418/927https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/418/927https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/418/927http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/418/927GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/418/927/table2 (Parameters of sources (including multiple identifications))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/418/927/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/418/927/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/418/927/table2?GETtext/xml+votable180.050000true1.2776-69.08690.005555555555555556RXTE6/87 557 597 611 845 1196 1405 1699 1701 2012 2388 2564 2623 2684 2759 3075 4439 4482 4790 5423 5439 5584 5609 5975 6017 6097 6883 6911 6977 7026 7244 7548 7551 7606 7642 7711 7752 7869 7969 7980 8071 8220 8271 8385 8520 8923 9354 9470 9477 9512 9612 9711 9999 10124 10312 10379 10484 10527 10604 10716 10912 10927 10977 11388 11557 11591 11898 12024 12121 12405 12921 13414 13875 13927 14777 14858 15090 15112 15135 15164 15295 15357 15969 16186 16301 16333 16434 16542 16642 16671 16816 16953 17075 17237 17727 17753 18484 18524 18566 18584 18590 18817 18918 19283 19383 19883 20099 20286 20489 20538 20618 21036 21439 21450 21763 22485 22577 22722 22854 22890 23027 23132 23191 23323 23451 24084 24120 24125 24297 24779 24848 24943 25035 25132 25622 25907 26082 26131 26140 26148 26183 26209 26292 26302 27730 27765 27773 27862 28251 28479 28517 28934 29360 29404 29795 30753 30873 30946 30993 31121 31745 31774 31806 31902 32344 32484 32500 32624 32891 32951 33034 33049 33091 33098 33113 33164 33235 33295 33298 33349 33440 33628 33713 33795 33864 33930 34104 34139 34243 34881 35049 35055 35623 36957 36985 37475 38268 38653 38853 39077 39456 40007 40777 40809 41077 41081 41087 41135 41151 41240 41252 41279 41326 41951 42016 42076 42308 42646 42658 42666 42683 42809 42901 42910 42981 43236 43262 43270 43282 43286 43302 43321 43357 43382 43412 43416 43458 43472 43477 43503 43544 43627 43633 43667 43679 43723 43825 43831 43838 43849 43863 43877 43939 43947 43977 43983 44009 44046 44052 44262 44450 44529 44557 44796 44908 45197 45222 45235 45423 45499 45741 45855 45883 45984 46119 46399 46615 46987 47014 47016 47047 47122 47154 47162 47169 47244 47375 47805 47866 48034 48263 48394 49022 49042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/418/927?format=asciiX-raydefaultJ/A+A/418/927/table2Parameters of sources (including multiple identifications)recnoRecord number assigned by the VizieR team.
