cds-question@unistra.frgamma-ray-astronomysurveysWe present a catalog of point gamma-ray sources detected by the EGRET detector on the Compton Gamma Ray Observatory. We used the entire gamma-ray dataset of reprocessed photons at energies above 100MeV and new Galactic interstellar emission models based on CO, HI, dark gas, and interstellar radiation field data. Two different assumptions are used to describe the cosmic-ray distribution in the Galaxy to analyse the systematic uncertainties in source detection and characterization. We applied a 2-dimensional maximum-likelihood detection method similar to that used to analyze the 3rd EGRET catalogue. The revised catalogue lists 188 sources, 14 of which are marked as confused, in contrast to the 271 entries of the 3rd EGRET (3EG) catalogue. We do not detect 107 sources discovered previously because additional structure is present in the interstellar background.2008A&A...489..849Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/489/849CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/123/79 : Third EGRET catalog (3EG) (Hartman+, 1999)J/ApJS/135/155 : Radio identification of 3EG EGRET sources (Mattox+, 2001)J/ApJS/157/324 : EGRET high-energy cosmic photons (E>10GeV) (Thompson+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/489/849https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/489/849http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/489/849https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/489/849https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/489/849http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/489/849GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/489/849/egr (EGR catalogue of 174 sources (tableA1 in the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/489/849/egr?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/489/849/egr?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/489/849/egr?GETtext/xml+votable180.050000true2.0173.140.0055555555555555566/436 515 556 582 672 909 1085 2414 2860 3308 3651 3819 4695 4822 5423 5816 5846 6070 6640 6646 6822 7004 7383 7426 7576 7896 7960 7970 8512 9248 9442 9460 9632 9715 9723 10340 10526 11075 12240 12441 12475 12671 13499 13607 13687 13768 13927 14620 14641 14692 14696 14750 15116 15310 15643 15925 17236 18155 18208 18496 18715 19333 19396 19421 20099 20105 20472 20554 20647 21121 21774 21974 22255 22517 22930 22947 23015 23099 23124 23309 23417 23547 23686 23952 23995 24084 24185 24269 24831 24906 25022 25065 25214 25630 25654 25791 25864 26118 26131 26140 26159 26292 26342 26980 28081 28479 28495 28675 28814 28830 28849 28894 28913 29009 29016 29074 29469 29505 29570 29592 29614 29720 29761 30114 30241 30247 30416 30860 31002 31107 31187 31665 32137 32614 32934 33091 33580 33605 33827 34123 34262 34423 35078 35304 36187 36845 37342 37928 37936 38017 38081 39023 39131 39198 39237 39241 39962 40760 41595 41685 42143 42207 42384 42863 42901 42978 42980 43261 43361 43822 44244 44800 44813 44908 45218 45373 46066 46279 46310 46964 47014 47107 47462 47862 47873 47938 48677 49070https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/489/849?format=asciiGamma-raydefaultJ/A+A/489/849/egrEGR catalogue of 174 sources (tableA1 in the paper)recnoRecord number assigned by the VizieR team.
