cds-question@unistra.frsurveysradio-continuum-emissionradio-sourcesinfrared-photometryWe have previously presented the results of a 325MHz radio survey of M31 (Cat. <J/ApJS/155/89>, conducted with the A configuration of the Very Large Array. In this survey, a total of 405 radio sources between <~6" and 170" in extent were mapped with a resolution of 6" and a sensitivity of ~0.6mJy/beam. Here we compare the resultant source list and image with other radio, IR, optical, and X-ray observations and catalogs of the region.2005ApJS..159..242Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/159/242CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/155/89 : 325MHz radio survey in M31 (Gelfand+, 2004)J/A+AS/61/451 : The 37W catalogue of radio sources in M31 (Walterbos+ 1985)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003)II/208 : BVRI CCD photometry in the field of M 31 (Magnier+ 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/159/242https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/159/242http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/159/242https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/159/242https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/159/242http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/159/242GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/159/242/table6 (IR magnitude and colors of 2MASS PSC (Cat. <II/246>) counterparts of GLG sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/159/242/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/159/242/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/159/242/table6?GETtext/xml+votable180.050000true10.61091666741.3012833330.005555555555555556Cone search capability for table J/ApJS/159/242/table8 (GLG sources with a good match in the MagOpt catalog (Cat. <II/208>))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/159/242/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/159/242/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/159/242/table8?GETtext/xml+votable180.050000true10.59162541.1336055560.005555555555555556Cone search capability for table J/ApJS/159/242/table9 (Good X-ray counterparts of GLG sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/159/242/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/159/242/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/159/242/table9?GETtext/xml+votable180.050000true10.8597541.3200111110.005555555555555556Cone search capability for table J/ApJS/159/242/table1 (Steep spectrum ({alpha}<-1.3) GLG sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/159/242/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/159/242/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/159/242/table1?GETtext/xml+votable180.050000true10.61091666741.3012833330.005555555555555556Cone search capability for table J/ApJS/159/242/table2 (Flat spectrum (-0.5<{alpha}<0.5) GLG sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/159/242/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/159/242/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/159/242/table2?GETtext/xml+votable180.050000true10.71504166741.4428694440.005555555555555556Cone search capability for table J/ApJS/159/242/table3 (GLG sources with spectral turnover ({phi}>=3{sigma}_{phi}_))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/159/242/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/159/242/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/159/242/table3?GETtext/xml+votable180.050000true10.90066666741.337850.005555555555555556Cone search capability for table J/ApJS/159/242/table5 (IR magnitudes and colors of 2MASS Extended Source Catalog (Cat. <VII/233>) counterparts of GLG sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/159/242/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/159/242/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/159/242/table5?GETtext/xml+votable180.050000true10.46591666741.4117638890.0055555555555555565/677 6/2619 2621 2622 2623 2664 2666 2667 2705 27522.1534725313611987e-25 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/159/242?format=asciiInfraredRadiodefaultJ/ApJS/159/242/table6IR magnitude and colors of 2MASS PSC (Cat. <II/246>) counterparts of GLG sourcesGLGGLG source namemeta.id;meta.mainintTypeSource type (G1)src.classcharrecnoRecord number assigned by the VizieR team.
