cds-question@unistra.frgalaxy-planesmilky-way-galaxyThe Swift Deep Galactic Plane Survey is a Swift Key Project consisting of 380 tiled pointings covering 40 sq. deg of the Galactic Plane between longitude 10<|l|<30 deg and latitude |b|<0.5 deg. Each pointing has a 5ks exposure, yielding a total of 1.9Ms spread across the entire survey footprint. Phase-I observations were carried out between March 2017 and May 2021. The Survey is complete to depth >1*10^34^erg/s to the edge of the Galaxy. The main Survey goal is to produce a rich sample of new X-ray sources and transients, while also covering a broad discovery space. Here, we introduce the Survey strategy and present a catalog of sources detected during Phase-I observations. In total, we identify 928 X-ray sources, of which 348 are unique to our X-ray catalog. We report on the characteristics of sources in our catalog and highlight sources newly classified and published by the DGPS team.2023ApJS..269...49Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/269/49CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/269/49https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/269/49http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/269/49https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/269/49https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/269/49http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/269/49GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/269/49/table2 (DGPS phase-I catalog of sources with an LSXPS counterpart)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/269/49/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/269/49/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/269/49/table2?GETtext/xml+votable180.050000true259.33791-38.397670.005555555555555556Cone search capability for table J/ApJS/269/49/table3 (DGPS phase-I sources without an LSXPS counterpart)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/269/49/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/269/49/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/269/49/table3?GETtext/xml+votable180.050000true246.93269-48.535210.0055555555555555565/7376 7383 7564 10543 10556 10595 6/29090-29091 29096-29097 29100-29101 29112 29114-29115 29118-29119 29457 29460-29461 29508 29510-29511 29517 29522-29523 29528-29529 30216 30218-30219 30222 30241 30244-30245 30262 42158-42159 42169-42171 42206-42207 42210-42211 42214-42217 42228-42229 42378-42379 42387 42390-42393 42396-42397 42400 42434-42435 42438-42441 42444-42445 42500https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/269/49?format=asciiX-raydefaultJ/ApJS/269/49/table2DGPS phase-I catalog of sources with an LSXPS counterpartrecnoRecord number assigned by the VizieR team.
