cds-question@unistra.frinfrared-sourcesmillimeter-astronomysubmillimeter-astronomymolecular-cloudsinterstellar-mediumWe present results from a survey of a 1300arcmin^2^ region of the Orion B South molecular cloud, including NGC 2024, NGC 2023, and the Horsehead Nebula (B33), obtained using the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope (JCMT). Submillimeter continuum observations at 450 and 850{mu}m are discussed. Using an automated algorithm, 57 discrete emission features ("clumps") are identified in the 850{mu}m map.2006ApJ...639..259Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/639/259CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/559/307 : Sub-mm mapping in Orion B molecular cloud (Johnstone+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/639/259https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/639/259http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/639/259https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/639/259https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/639/259http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/639/259GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/639/259/clumps (Clump properties in Orion South B molecular cloud)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/639/259/clumps?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/639/259/clumps?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/639/259/clumps?GETtext/xml+votable180.050000true85.215833-1.880.0055555555555555566/22854 22855https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/639/259?format=asciiInfraredRadiodefaultJ/ApJ/639/259/clumpsClump properties in Orion South B molecular cloudCDegree of concentration (3)meta.notefloatrecnoRecord number assigned by the VizieR team.
