cds-question@unistra.frgamma-ray-astronomyThis supplement extends the second EGRET catalog of high-energy gamma-ray sources (see recent paper by Thompson et al.), incorporating data from 1993 September to 1994 October. The second catalog contained 129 sources, based on data from 1991 April to 1993 September. An additional 28 sources are found, including three new identifications of active galactic nuclei.1996ApJS..107..227Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/107/227CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/94/551 : The first EGRET catalog (Fichtel+ 1994)J/ApJS/101/259 : The second EGRET catalog (Thompson+ 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/107/227https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/107/227http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/107/227https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/107/227https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/107/227http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/107/227GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/107/227/table1 (EGRET Viewing Periods: Phase 3)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/107/227/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/107/227/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/107/227/table1?GETtext/xml+votable180.050000true128.922-45.17850.005555555555555556Cone search capability for table J/ApJS/107/227/table2 (Supplement to the Second EGRET Source Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/107/227/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/107/227/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/107/227/table2?GETtext/xml+votable180.050000true66.6616.610.005555555555555556CGRO6/173 2019 3089 5314 7592 7882 7896 10251 14413 14428 15502 18718 18930 19283 19626 21393 22877 22947 23545 23588 23952 24451 25022 25596 26156 26983 27652 27677 27727 27754 27765 27767 27960 28492 28675 28767 28848 28964 29235 29490 29505 29836 30423 30806 31291 32756 34023 36958 38143 39023 39235 39249 41334 41654 41685 42205 42237 42874 43262 43366 44813 47805 48874https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/107/227?format=asciiGamma-raydefaultJ/ApJS/107/227/table1EGRET Viewing Periods: Phase 3recnoRecord number assigned by the VizieR team.
