cds-question@unistra.frsurveysmolecular-cloudsgalaxy-classification-systemsradio-astronomyWe have carried out an H^13^CO^+^ (J=1-0) core survey in a large area of 1.5degx0.5deg, covering the whole region of the Orion A molecular cloud, using the Nobeyama 45m radio telescope with the 25 Beam Array Receiver System (BEARS). This survey is unique in that a large area (~48pc^2^) of the cloud was covered with a high spatial resolution of 21" (0.05pc) and with a deep integration (1sigma~0.1K in T*_A_), resulting in a core mass detection of 1.6M_{sun}_. The morphology of the H^13^CO^+^ (J=1-0) emission is very similar to that of the 850um continuum emission. We identified 236 dense cores from our data with the clumpfind algorithm. The cores are close to virial equilibrium, independent of whether they are thermal or turbulent.2007ApJ...665.1194Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/665/1194CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/109/709 : K survey of Ori A molecular cloud (Ali+ 1995)J/ApJ/653/383 : SCUBA observations in Orion A South region (Johnstone+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/665/1194https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/665/1194http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/665/1194https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/665/1194https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/665/1194http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/665/1194GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/665/1194/table1 (Physical properties of the H^13^CO^+^ cores in the Orion A cloud)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/665/1194/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/665/1194/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/665/1194/table1?GETtext/xml+votable180.050000true83.653333-5.6802780.0055555555555555566/21436 21438 21439 22805https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/665/1194?format=asciiOpticalRadiodefaultJ/ApJ/665/1194/table1Physical properties of the H^13^CO^+^ cores in the Orion A cloudrecnoRecord number assigned by the VizieR team.
