cds-question@unistra.frgalaxiesx-ray-sourcessurveysThis paper reports the results of the analysis of the second ROSAT PSPC survey of M 31 performed in summer 1992. We compare our results with those of the first survey, already published in Supper et al. (1997, Cat. <J/A+A/317/328>). Within the ~10.7deg^2^ field of view, 396 individual X-ray sources are detected in the second survey data, of which 164 are new detections. When combined with the first survey, this result in a total of 560 X-ray sources in the field of M 31. Their (0.1keV-2.0keV) fluxes range from 7x10^-15^erg/cm^2^/s to 7.6x10^-12^erg/cm^2^/s, and of these 560 sources, 55 are tentatively identified with foreground stars, 33 with globular clusters, 16 with supernova remnants, and 10 with radio sources and galaxies (including M 32). A comparison with the results of the Einstein M 31 survey reveals 491 newly detected sources, 11 long term variable sources, and 7 possible transient sources. Comparing the two ROSAT surveys, we come up with 34 long term variable sources and 8 transient candidates.2001A&A...373...63Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/373/63CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/144 : Brightest stars in the field of M31 (Berkhuijsen+ 1988)IX/30 : Second ROSAT PSPC Catalog (ROSAT, 2000)IX/13 : The 2E Catalogue (Harris+ 1994)J/ApJS/118/177 : JHK photometry of M31 spiral arm (Kodaira+, 1998)J/ApJ/504/113 : F175W and F275W photometry of M31 and M32 (Brown+, 1998)J/ApJ/324/172 : M31 UBVR photometry (Hodge+, 1988)J/A+A/278/36 : M 31 new OB associations (Magnier+ 1993)J/A+A/317/328 : ROSAT PSPC survey of M 31 (Supper+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/373/63https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/373/63http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/373/63https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/373/63https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/373/63http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/373/63GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/373/63/table5 (All X-ray sources found with the ROSAT PSPC during the second M31 survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/373/63/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/373/63/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/373/63/table5?GETtext/xml+votable180.050000true9.09041740.8936110.005555555555555556Cone search capability for table J/A+A/373/63/table6 (All X-ray sources coming out of a merge of the source lists from the first and second M31 survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/373/63/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/373/63/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/373/63/table6?GETtext/xml+votable180.050000true9.09041740.8936110.0055555555555555566/2619 2622-2623 2666-2667 2705 2708-2710 2752-2753https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/373/63?format=asciiX-raydefaultJ/A+A/373/63/table5All X-ray sources found with the ROSAT PSPC during the second M31 surveyrecnoRecord number assigned by the VizieR team.
