cds-question@unistra.frx-ray-sourcesx-ray-binary-starsgalaxiesX-ray observations have revealed in other galaxies a class of extranuclear X-ray point sources with X-ray luminosities of 10^39^-10^41^ergs/s, exceeding the Eddington luminosity for stellar mass X-ray binaries. These ultraluminous X-ray sources (ULXs) may be powered by intermediate-mass black holes of a few thousand M_Sun_ or stellar mass black holes with special radiation processes. In this paper, we present a survey of ULXs in 313 nearby galaxies with D_25_>1 within 40Mpc with 467 ROSAT High Resolution Imager (HRI) archival observations. The HRI observations are reduced with uniform procedures, refined by simulations that help define the point source detection algorithm employed in this survey. A sample of 562 extragalactic X-ray point sources with L_X_=10^38^-10^43^ergs/s is extracted from 173 survey galaxies, including 106 ULX candidates within the D_25_ isophotes of 63 galaxies and 110 ULX candidates between 1D_25_ and 2D_25_ of 64 galaxies, from which a clean sample of 109 ULXs is constructed to minimize the contamination from foreground or background objects.2005ApJS..157...59Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/157/59CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/28 : ROSAT HRI Pointed Observations (1RXH) (ROSAT Team, 2000)VII/155 : RC3 (de Vaucouleurs+ 1991)J/ApJS/154/519 : Properties of ultraluminous X-ray candidates (Swartz+, 2004)J/A+A/429/1125 : Catalog of Ultraluminous X-ray sources (Liu+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/157/59https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/157/59http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/157/59https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/157/59https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/157/59http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/157/59GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/157/59/table1 (Properties of surveyed galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/157/59/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/157/59/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/157/59/table1?GETtext/xml+votable180.050000true11.7864-20.76320.005555555555555556Cone search capability for table J/ApJS/157/59/table2 (X-ray sources in surveyed galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/157/59/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/157/59/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/157/59/table2?GETtext/xml+votable180.050000true11.7929167-20.78630560.0055555555555555565/8633 6/2282 2409 3504 3506 3507 4127 4149 4439 4447 4469 4511 4682 5202 5241 5342 5398 5429 5607 5773 5793 5796 5975 5978 5981 6034 6040 6045 6047 6057 6093 7132 7424 7536 7606 7624 7642 7662 7743 7799 7876 7878 7896 8028 8042 8106 8173 8195 8196 8225 8492 9882 10385 10396 10454 10475 10637 10755 10761 10769 10817 10841 10856 10888 10905 10911 10912 10925 10927 10935 10941 10977 10979 10982 10991 11026 11027 11084 11112 11127 11227 11246 11253 11434 11580 11639 11734 11738 11791 11961 12025 12122 13330 13336 13488 13489 15161 15592 15593 16108 16655 16664 16666 16701 16898 17472 17752 17754 17755 17780 18032 18212 18642 18809 18935 19614 20014 21155 24681 24777 24949 24951 25083 25135 25647 25768 25907 26125 26148 26175 26214 26271 26303 26309 26313 26314 26336 26340 26803 27186 27515 27555 27604 27669 27714 27719 27721 27728 27730 27736 27765 27767 27773 27861 27907 27918 27934 27936 27937 27945 27948 27949 27955 28015 28033 28035 28049 28141 28154 28167 28173 28184 28299 28495 28496 28521 28524 28534 28535 28538 28541 28631 28637 31998 33193 33228 33920 33921 33952 33954 33958 33984 34018 34251 34272 34343 34471 34492 34493 34495 34531 34540 34541 34692 34694 35536 35538 35691 35993 36107 36141 36152 36194 36231 36785 37429 38853 40410 43262 43263 43604 43881 46399 46442 46568 46598 46615 46660 46662 46832 46987 47047 470583.3107421909657627e-21 3.3107421909657627e-21https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/157/59?format=asciiX-raydefaultJ/ApJS/157/59/table1Properties of surveyed galaxiesrecnoRecord number assigned by the VizieR team.
