cds-question@unistra.frinterstellar-mediummolecular-cloudsinfrared-sourcesWe present results from a survey of a 900 arcmin^2^ region of the Orion B molecular cloud, including NGC 2068, NGC 2071, and HH 24/25/26, at 850{mu}m using the Submillimeter Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope. Following the techniques developed by Johnstone et al. (2000ApJ...545..327J), we identify 75 independent objects and compute size, flux, and degree of central concentration. Comparison with isothermal, pressure-confined, self-gravitating Bonnor-Ebert spheres implies that the clumps have internal temperatures of 20-40K and surface pressures 5.5<log(P/k)[CGS]<6.5. The clump masses span 0.2-12.3M_{sun}_ assuming typical dust temperatures and a dust emissivity {kappa}_850_=0.01cm^2^/g.2001ApJ...559..307Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/559/307CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/559/307https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/559/307http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/559/307https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/559/307https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/559/307http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/559/307GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/559/307/table1 (850{mu}m clump properties in Orion B North)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/559/307/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/559/307/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/559/307/table1?GETtext/xml+votable180.050000true86.516667-0.2480560.0055555555555555566/22873 22876https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/559/307?format=asciiInfrareddefaultJ/ApJ/559/307/table1850{mu}m clump properties in Orion B NorthrecnoRecord number assigned by the VizieR team.
