cds-question@unistra.frpulsarsDiscovery of pulsars is one of the main goals for large radio telescopes. The Five-hundred-meter Aperture Spherical radio Telescope (FAST), that incorporates an L-band 19-beam receiver with a system temperature of about 20 K, is the most sensitive radio telescope utilized for discovering pulsars. We designed the snapshot observation mode for a FAST key science project, the Galactic Plane Pulsar Snapshot (GPPS) survey, in which every four nearby pointings can observe a cover of a sky patch of 0.1575 square degrees through beam-switching of the L-band 19-beam receiver. The integration time for each pointing is 300 seconds so that the GPPS observations for a cover can be made in 21 minutes. The goal of the GPPS survey is to discover pulsars within the Galactic latitude of +/-10{deg} from the Galactic plane, and the highest priority is given to the inner Galaxy within +/-5{deg}. Up to now, the GPPS survey has discovered 201 pulsars, including currently the faintest pulsars which cannot be detected by other telescopes, pulsars with extremely high dispersion measures (DMs) which challenge the currently widely used models for the Galactic electron density distribution, pulsars coincident with supernova remnants, 40 millisecond pulsars, 16 binary pulsars, some nulling and mode-changing pulsars and rotating radio transients (RRATs). The follow-up observations for confirmation of new pulsars have polarization-signals recorded for polarization profiles of the pulsars. Re-detection of previously known pulsars in the survey data also leads to significant improvements in parameters for 64 pulsars. The GPPS survey discoveries are published and will be updated at http://zmtt.bao.ac.cn/GPPS/.2021RAA....21..107Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/21.107CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://zmtt.bao.ac.cn/GPPS : GPPS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RAA/21.107https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/21.107http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/21.107https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/21.107https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/21.107http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/21.107GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RAA/21.107/table2 (A List of Pulsars Discovered by the GPPS Survey (See http://zmtt.bao.ac.cn/GPPS/ for Updates))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/21.107/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/21.107/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/21.107/table2?GETtext/xml+votable180.050000true285.35336.98330.005555555555555556Cone search capability for table J/other/RAA/21.107/table3 (Distant Pulsars with Excess DMs Challenging the Currently Widely Used Models)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/21.107/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/21.107/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/21.107/table3?GETtext/xml+votable180.050000true313.22173144.3602640.005555555555555556Cone search capability for table J/other/RAA/21.107/table5 (Binary Pulsars Discovered in the GPPS Survey (Sorted by Pulsar Period))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/21.107/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/21.107/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/21.107/table5?GETtext/xml+votable180.050000true284.89791673.21666670.005555555555555556Cone search capability for table J/other/RAA/21.107/table7 (Polarization Parameters of Eight Newly Discovered Pulsars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/21.107/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/21.107/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/21.107/table7?GETtext/xml+votable180.050000true282.07958331.44997220.0055555555555555565/7578-7579 7601 7604-7605 7650-7651 6/12943 12967 12970-12971 12974 12991 13051 13053 13218 14051 14337 14355 14359 14402-14403 14413 14421 14592 14594 14605 14625 14645 14666-14667 14696 15368 15370 30271 30306-30307 30310-30311 30329-30331 30334 30357 30359 30400-30401 30413 30425 30428-30429 30431 30449 30453 30594-30595 30597-30599 30608 30610 30618-30619 30622-30623 30628-30629 30632 30640-30641 30643-30644 30647 30664 30671 30689-30693 30695-30696 30700 30702-30703 30707 30712-30713 30716 30718-30719 32084-32085 320878.282586962885013e-25 8.282586962885013e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RAA/21.107?format=asciiRadiodefaultJ/other/RAA/21.107/table2A List of Pulsars Discovered by the GPPS Survey (See http://zmtt.bao.ac.cn/GPPS/ for Updates)SimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
