cds-question@unistra.frmolecular-cloudsinfrared-photometryradio-continuum-emissionWe report on a wide-field submillimeter continuum survey of the NGC 2068/2071 protoclusters in the Orion B cloud complex. We used the SCUBA bolometer array on JCMT to map a 32'x18' region in size (~4pcx2pc) at 850 and 450 microns. Our survey shows that the dense cores mapped in CS(2-1) by Lada et al. (1991ApJ...368..432L) and labelled with LBS numbers break up into 82 small-scale (~5000AU) fragments. The latter include 70 starless condensations, believed to be the immediate progenitors of accreting protostars, and 5 circumstellar envelopes/disks around protostars. The nature of the 7 remaining cloud fragments is unclear because their dust continuum emission is largely contaminated by line emission.2001A&A...372L..41Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/372/L41CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/372/L41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/372/L41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/372/L41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/372/L41https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/372/L41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/372/L41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/372/L41/table1 (Protocluster condensations identified in NGC 2068/2071)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/372/L41/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/372/L41/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/372/L41/table1?GETtext/xml+votable180.050000true86.61750.3247220.0055555555555555566/22873 22876https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/372/L41?format=asciiInfraredRadiodefaultJ/A+A/372/L41/table1Protocluster condensations identified in NGC 2068/2071recnoRecord number assigned by the VizieR team.
